Meet Johns- Hopkins Trained Dermatologist

Rebecca Kazin, MD

Dr. Kazin is a John Hopkins- trained, nationally recognized expert in skin and hair.

"For over two decades I've cared for my patients and listened to their concerns. But year after year I'd hear them struggle the same problem- having to choose between an itchy scalp or having frizz-free hair.

They were forced to choose between harsh drug store products that left their hair lifeless, or using the brands they loved but suffering through the itch.

I took time to think about this problem and finally I thought of an answer.

I decided to create haircare products with ingredients proven to soothe and treat the scalp but add skincare ingredients to enhancing the health of the hair."

Finally, Hair Sanity.

"Driven by the unmet needs of my patients, I put together a team of renown dermatologists and cosmetic chemists. It took five years of formulating and rigorous testing but I'm proud to have created HairSanity- a system of truly effective, life-improving products.

To ensure my products meet her personal standards, I have personally tested every formula. In fact, my entire family, including my parents, husband and three daughters use Hairsanity!

My passion extends to caring for each customer. I read every question, comment and review. I personally reply to each message, making sure each person is heard.

Hairsanity has been a passion project requiring countless hours and immense effort but I remain dedicated to my loyal customers who have found that nothing works as well as HairSanity. I ultimately want to provide them with the relief and care they truly deserve."

Clinically Proven Active Ingredients

Powered by 1% Hydrocortisone Acetate, HairSanity helps calm scalp itch, redness, flaking, and irritation at the source.

We pair this dermatologist-trusted active with scalp-supporting ingredients like Willow Bark, Sea Whip, and Alp Rose to cleanse gently, soothe discomfort, and help hair feel soft, hydrated, and healthy-looking.

Flakes, itch, irritation — it's not just You.

Stress, product buildup, pollution and harsh hair treatments can trigger your head of suffering, but most 'solutions' only mask the problem.

Treat your scalp like you treat your skin.

Hair Sanity's dermatologist-developed, head-to-toe system soothes irritation and nourishes both scalp and hair—without extra steps or harmful ingredients.

Promises, not compromises.

Clinically tested and backed by real data, our formulas deliver exactly what we promise—no filler ingredients, just science.

Frequently Asked Questions

Why did Dr. Kazin create HairSanity for her patients?

Throughout her career, Dr. Kazin was repeatedly approached by patients seeking to solve problems with dry or oily scalp, flaking and scalp itch.

How do I know HairSanity will improve my scalp and hair?

Over 700 people tested our two-step solution over 4 weeks with clear results: 96% of participants had a reduction in scalp dryness, 89% had a reduction in scalp flaking.

What active ingredients make HairSanity so safe and effective?

Step 1 of HairSanity contains hydrocortisone acetate, the #1 ingredient for itch and irritation used by dermatologists worldwide in skin and scalp care.

What makes HairSanity different from other products on the market?

Most drugstore products address the scalp with zinc pyrithione and many contain sulfates and parabens. We take a completely different approach and have eliminated zinc pyrithione, sulfates, and parabens.

How soon will I see and feel my healthier scalp and hair?

Most will see and feel results after a few washes, but the full effects are most noticeable after 4 weeks of consistent use at least 3 times per week.

Is HairSanity safe for sensitive skin?

By eliminating harsh surfactants, parabens, and allergenic preservatives, HairSanity can be used on sensitive skin and scalp.

How do I get the best results with HairSanity?

Simply apply a quarter-sized amount of HairSanity Step 1 to the top of the head and another quarter-sized amount to the sides of wet hair and scalp.

Is HairSanity gentle on color and keratin?

HairSanity does not use harsh surfactants (cleansers) to clean the hair as many drugstore shampoos do. Harsh surfactants can prematurely strip color and keratin from the hair.

Once my scalp and hair look and feel great, do I continue with HairSanity?

Once HairSanity improves your scalp and hair, you can continue HairSanity to keep your scalp calm and flake-free. You'll also maintain your hydrated, frizz-free, healthy hair.

How often can I use HairSanity to get the best results?

We recommend using HairSanity every time you wash your hair — ideally at least 3 times per week.
