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."
