The Science Behind Scalp Scrubs: Unlocking the Secret to Hair Health
Jan 12, 2024 | By Maria Eliza Pineda
Scalp scrubs are quickly becoming a staple in most hair care routines. Much like a hair mask or hair treatment, a scalp scrub is a product that shouldn’t be used daily but is incredibly beneficial if used on a weekly basis or so. But is this just hearsay or is there actual science that can back this up? Find out the science behind scalp scrubs and how this powerful product can improve your hair care routine by a mile.
A Closer Look at Exfoliation
Scientific research has shown the benefits of scalp exfoliation.
- This 2016 study highlights the effects of regular hair cleansing as well as exfoliation on people dealing with skin conditions on the scalp like seborrheic dermatitis. Washing and exfoliating improved scaling and itchiness on the scalp and decreased bacteria levels.
- A study conducted by the International Journal of Trichology in 2018 showed that flaking can happen within 1-2 weeks if the hair is not properly washed or exfoliated. This leads to an increase in dandruff and the accumulation of dead skin.
- In the Journal of Clinical Medicine, increased blood flow and direct stimulation of the hair follicle has been shown to significantly boost hair growth and improve the health of the hair.
How Scrubbing Helps:
So, how exactly does scrubbing your scalp help? From scientific studies, we already know that they have multiple benefits. But how does it work and why should you be scrubbing regularly?
Here’s a simple breakdown of how scalp scrubs work to keep your hair and scalp in tip-top shape:
Exfoliation is Key
You may already know how important exfoliation is to the rest of the skin on your body. You regularly exfoliate your face and your body to get soft, smooth, and clear skin. The same goes for your scalp. By getting rid of the dead skin on your scalp, you clear out blockages that may be causing roughness, hindered hair growth, irritation, flaking, and hindered nutrient absorption. A clear and exfoliated scalp is the path to healthy hair growth.
Improves Circulation
This is another easy equation. What do you do when your leg is feeling numb and the circulation isn’t great? You stimulate it! You move it around, massage it, and voila, it feels better. It’s the same with the scalp; physical stimulation like massaging and scrubbing increases blood flow and improves circulation in the scalp. This, in turn, boosts hair growth and gives a better environment for your hair to grow in.
Combats Scalp Issues
Scalp conditions such as dandruff, dermatitis, irritation, greasiness, and dryness can be improved by using a scalp scrub regularly. This is because exfoliation regulates the scalp cell turnover and sebum production. However, if dealing with any other conditions, make sure to consult a professional before using any products.
It’s Not One-Size-Fits-All
While there is already existing scientific data of the benefits of scalp scrubs, research is still ongoing and there is still so much more to know. Hopefully, more research will be done pertaining to scalp scrubs, scalp exfoliation, and different ingredients for more targeted data.
That’s because hair care is not one-size-fits-all. Different ingredients work for different concerns, hair types, and preferences. The choices for scalp scrubs should be as extensive as shampoos, conditioners, and hair masks to suit the needs of different people.
With that said, the existing evidence is promising and a great starting point for further research. In the years to come, more scientists and companies are sure to put in the time and effort to know more about how to improve this product and cater to different individuals.
Reminders
Natural Ingredients
Always be aware of the product ingredients you’re using or trying out. Make sure to always look for gentle, natural ingredients and avoid harsh or harmful chemicals. Choose a scalp scrub that contains vegan ingredients and a gentle exfoliant that will not irritate the skin.
Patch Test
Another must is patch testing. No matter what product you’re trying for the first time, always do a patch test first before using the product fully. Apply a small amount to an inconspicuous area and observe. If there are no adverse side effects, you can continue. If you notice any kind of irritation, stop immediately.
Pace Yourself
It’s important to note that there is such a thing as over-exfoliation. This happens if you exfoliate too often or if you are too abrasive with it. Pace yourself and start with once-a-week use. Observe the results and adjust accordingly to your hair and scalp’s needs. Also, be gentle. Do not use excessive force.
Aftercare
Exfoliation is best paired with good shampooing and conditioning right after to cleanse away the dead skin and restore nutrition and moisture in the hair and scalp.
