Is a Scalp Care Routine Actually Vital? Here is What Consultants Say

I’ve been within the skincare trade for over 30 years now, so I’ve undoubtedly seen my fair proportion of tendencies come and go. A few of them had benefit, however as a rule, they didn’t dwell as much as the thrill and so they turned out to be simply one other passing fad.

The most recent pattern to come back about—which might be fueled a minimum of partly by social media—is all about scalp care. Skincare manufacturers are launching scalp-specific merchandise and individuals are sharing their private scalp care routines on Instagram and Tik Tok. However is a scalp care routine actually vital? Is that this simply one other short-lived pattern or is there actual worth to this?

On this put up, I’ll share my ideas on this matter. I’ll additionally talk about frequent scalp points and reply continuously requested questions with the assistance of two wonderful consultants. The primary is board-certified dermatologist Dr. Laura Speck, and the second is NYC trichologist, hair well being professional, and host of Hair Like Hers Podcast, Shab Reslan.

First, Is the Pores and skin on the Scalp Any Completely different From the Pores and skin on the Face?

From a physiological standpoint, the pores and skin on the scalp is thicker than the pores and skin on the remainder of the physique. It has numerous blood vessels and capillaries that connect with and provide hair follicles. It additionally has numerous sebaceous glands. In truth, it’s one of the crucial closely populated sebaceous gland areas on the entire physique, which explains why most peoples’ hair will get significantly greasy after it’s not washed for some time.

Regardless that scalp pores and skin is thicker than the pores and skin on different areas of the physique, it’s very delicate. For that reason, it might be extra vulnerable to points than facial pores and skin. Take it from Reslan, who says, “because of the present nature of the surroundings and our life-style habits, our scalps require extra consideration than ever. Correct scalp care is usually ignored by many individuals for the reason that focus is principally on the aesthetic of the hair itself. Attributable to an increase in hair thinning and hair loss points, the main target is now shifting to the scalp and the significance of sustaining a wholesome scalp microbiome, particularly for girls. For the reason that scalp is an extension of our facial pores and skin, it equally has a pH stage, moisture ranges, and cells that profit from exfoliation and regeneration.” 

What Are A number of the Most Widespread Scalp Issues?

Dandruff

In response to Speck, one of the crucial frequent considerations (and the problem she sees probably the most in her personal sufferers) is dandruff. “The medical time period for that’s seborrheic dermatitis,” she says. “For adults, it sometimes begins within the late-20s and might ebb and move through the years.” 

Dandruff occurs when the pores and skin undergoes fast keratinization (that is when pores and skin cells reproduce too shortly). As a result of they’re replicating so quick, they’re not capable of harden and turn into flat and protecting. The consequence? The pores and skin isn’t tight and compressed, so it flakes off simply.

The reason for dandruff has been recognized for over 50 years. It’s attributable to a fungus referred to as malassezia furfur. This fungus feeds on extra sebum on the scalp after which secretes free fatty acids and different byproducts. It’s these free fatty acids that inflame and compromise the pores and skin on the scalp. In different phrases, it’s not essentially the fungus itself, however its byproducts.

To deal with dandruff, antifungal brokers like selenium oxide and zinc pyrithione are used. These brokers assist cease the overgrowth of the dandruff-causing fungi. For extra extreme instances of dandruff, there are prescription choices as nicely. In the event you assume you’ve got dandruff, Speck says you need to use an anti-dandruff shampoo 2-3 occasions per week. “The key’s, that you simply need to therapeutic massage it by means of the scalp and let it sit for 2-5 minutes earlier than rinsing it out. Comply with with the shampoo and conditioner of your selection for the size of your hair. If that isn’t reducing it, go to your dermatologist who can consider the reason for your flaking and provide you with a prescription if wanted.” 

Dermatitis

Right here’s an attention-grabbing reality for you—many occasions, when individuals are experiencing scalp flakiness, they’re not experiencing dandruff in any respect. As a substitute, they’re experiencing some type of irritation, whether or not that’s some form of dermatitis and even low-grade psoriasis. That’s why I all the time suggest consulting a dermatologist to get a prognosis. They’ve the skilled eye and data required to find out the distinction between dandruff and dermatitis. And really, in the event you attempt to deal with dermatitis or psoriatic pores and skin with dandruff shampoos, you may make issues worse!

Dryness

One other attention-grabbing reality concerning the scalp is that the pores and skin doesn’t change very a lot with age, other than pores and skin thickness and dryness. In one research, researchers discovered that scalp thickness elevated, and the flexibility of the pores and skin to remain hydrated decreased with age. Meaning transepidermal water loss, and subsequent pores and skin dryness and dehydration, are prone to improve with age.

On this occasion, hydrating scalp merchandise may come in useful. You may strive utilizing merchandise that comprise humectants. These are components that assist the pores and skin protect and retain moisture. They’re helpful for dehydrated pores and skin, particularly in the event you’re shampooing too usually and stripping your pores and skin of moisture (however extra on that in a bit).

What Type of Scalp Care Merchandise Are Out There, and Are They Vital?

Whereas there’s no scarcity of scalp care merchandise that declare to deal with virtually each concern and concern, I imagine they are often boiled down to a few important classes. There are scalp serums, scalp oils, and scalp exfoliators (or scalp scrubs). Let’s do a deep dive into every sort of product and talk about whether or not or not they will present any actual profit for the pores and skin on the scalp!

Scalp Serums

Similar to face serums, scalp serums are marketed as focused therapies to enhance the state of the pores and skin (and hair). Whereas it is a comparatively new product class, I believe they are often useful you probably have dry pores and skin and so they comprise the best components. Once more, search for humectants. These will assist replenish moisture and hold your scalp hydrated.

You may as well search for scalp serums which might be labeled as “microbiome-friendly” or one thing to that impact. We’re simply starting to be taught concerning the significance of the microbiome, however what we do know is that it’s essential to maintain it balanced. I  would additionally search for scalp serums with components that assist cut back or regulate oil since that may assist hold dandruff-causing fungi in verify.

Scalp Serums and Hair Loss

Some scalp serums declare to cut back or reverse hair loss, however I’m not bought on that. In truth, I’d warning towards utilizing any of those in your at-home scalp care routine. That’s as a result of there are numerous causes for hair loss, and usually talking, a scalp serum gained’t tackle the basis causes. That’s except it incorporates an ingredient referred to as minoxidil, which is the one authorised ingredient in america and Canada to assist regrow hair. If something, most of them are in all probability serving to to cut back breakage, which will be helpful, however they gained’t essentially goal hair loss immediately.

“If you’re experiencing hair loss or signs equivalent to an itchy or flaky scalp, see a dermatologist to have them diagnose the trigger,” Speck says. “They are going to information you thru what routine can be most helpful for you.” 

Scalp Oils

Scalp oils are simply that—plant oils used to nourish, moisturize, or deal with the scalp not directly. Personally, I believe scalp oils will be helpful since they moisturize the hair and stop breakage as new hair enters the expansion cycle. This may be particularly useful for individuals who have curly, coily, and textured hair because it reduces breakage and retains fragile hair lubricated.

Scalp oils are additionally helpful for anybody who has a dry scalp or is experiencing transepidermal water loss. They will present a barrier between the pores and skin and the air and assist cut back flaking and irritancy. Nevertheless, identical to if you’re coping with the pores and skin in your face, you would wish to hydrate your scalp first after which put oil on afterward. (Be sure you know the distinction between dry and dehydrated pores and skin.)

Once more, in the event you’re vulnerable to dandruff or have every other scalp situation, I wouldn’t suggest utilizing oils. In the event you do, it might imbalance your microbiome even additional, exacerbating the problem. I’d additionally keep away from scalp oils in the event you’re vulnerable to scalp odor. They might doubtlessly make it worse.

Scalp Exfoliants

Exfoliating merchandise are a well-liked a part of many at-home scalp care routines. The concept is that the pores and skin on the scalp requires common exfoliation, identical to the remainder of the pores and skin. Like all different exfoliants, they are often cut up into two classes—bodily and chemical.

Bodily Exfoliants

The preferred scalp exfoliants appear to be salt or sugar-based scrubs. I’m not a giant fan of those for a few causes. The primary is that it’s troublesome for these tiny particles to get previous strands of hair. In truth, a lot of them by no means make it to the scalp in any respect. So, they will’t roll throughout the pores and skin and slough away useless cells like they’re presupposed to.

The second motive is that each salt and sugar dissolve in water. This implies they’ll dissolve quickly on moist hair. Once more, this implies they won’t slough away useless cells as successfully as some individuals assume.

Chemical Exfoliants

Lately, although, there’s been a rise in chemical exfoliants for the scalp. Whereas I believe these will be helpful, they need to be used sparingly. In any case, the scalp is a fragile space. You don’t need to over-exfoliate it or expose it to too many lively components. “Low concentrations of exfoliating acids are protected for the scalp and shouldn’t be used every day however as an alternative used as supplemental weekly therapies very like your facial exfoliant,” Reslan says. “The 2 hottest exfoliating acids and protected percentages for the scalp getting used right now are salicylic (round 2%) and glycolic (round 7%).” 

In the event you do use chemical exfoliants in your scalp, ensure you’re defending it from the solar. In the event you’re not defending new, weak cells, you may incur harm. Over time, solar harm might result in an elevated propensity for irregular cells. I all the time suggest dusting an SPF-infused powder alongside your hairline, in search of shade, and carrying a hat if you’re exterior.

How Usually Ought to I Actually Be Utilizing Shampoo?

An enormous a part of any scalp care routine is shampooing. Nevertheless, with all of the speak of “coaching” your scalp and the “no-shampoo” motion, many individuals are confused about how continuously they need to be cleansing their hair and scalp.

In response to Speck, “the preferrred interval to scrub most hair sorts is each 2-3 days. Kind of continuously can result in over or underproduction of oil. That being stated, somebody with advantageous straight hair would err on the extra frequent aspect (ex: each 2 days), whereas African American hair is extra fragile and ought to be washed solely as soon as each 1-2 weeks.” 

The Superb Shampooing Methodology

The way in which you shampoo additionally issues. In response to Reslan, “The largest mistake individuals make when washing their hair will not be sufficiently cleaning the scalp and leaving product and/or sebum (pure oil) residue behind. For this reason scalp care merchandise are important in sustaining a wholesome and balanced scalp surroundings that may develop wholesome and powerful hair with none interruptions or hindrances.”  

That’s why she recommends shampooing twice. “I like to recommend two shampoos each time you wash your hair,” she says. “You must focus the shampoo in your roots and therapeutic massage gently in round motions to really assist take away build-up. I like to recommend solely operating the shampoo down your ends in the event you use styling merchandise commonly.”

Reslan says individuals usually overlook the nape of the neck and the perimeters of the pinnacle above the ears. That explains why it’s frequent to seek out flaking and irritation in these areas. “In the event you shampoo your hair sometimes, it may be more difficult to sufficiently cleanse your scalp because of the improve in product and sebum build-up,” she says. “You actually must be your personal choose and make sure that everytime you’re washing your hair, you’re eradicating all of the build-up, and your hair isn’t left feeling waxy or trying greasy because it dries.” 

What’s the Verdict?

For my part, scalp care merchandise, and a scalp care routine, aren’t completely vital. And really, I’d argue that most individuals don’t must do a lot to care for his or her scalps, other than utilizing shampoo and conditioner. Nevertheless, in the event you’re experiencing dryness otherwise you’re occupied with testing out this ever-expanding product class, go for it! There are numerous attention-grabbing merchandise on the market, and you need to check them out in the event you’re curious. On the finish of the day, in the event that they make a distinction for you, that’s nice!

As Reslan places it, “our scalp is an extension of our face and simply as distinctive for every particular person. Similar to we deal with the pores and skin on our face, our scalp deserves to be washed, exfoliated, nourished, and moisturized utilizing a topical.” 

In the event you’re experiencing a diagnosable scalp concern, although, I like to recommend skipping the scalp care merchandise and consulting a physician. Even when it’s a situation that doesn’t require treatment, you may relaxation assured understanding knowledgeable has checked it out. It’s all the time higher to be protected than sorry!
