“My struggle with hair loss began at age 30 after the birth of my son, Eli, and then continued after my second child, Ruby, several years later. As the years went by, my hair slowly started to restore itself. But then, at age 39, I suffered a stroke. The physical symptoms of the stroke, emotional stress, and a combination of medications brought my hair loss back with a vengeance.

After these big life events, I was desperate to return to my full self. I made countless trips to the drug store and consulted with experts - but I was left feeling lost, confused, and convinced that there was no effective and natural solution to help my hair.

So, one month after my stroke, I began a journey to find a safe, natural and effective solution for scalp and hair preservation and growth. I’m eager to share Collective Laboratories with the world — and help women everywhere shed the shame of hair loss and focus on a stronger, healthier version of themselves.”

Reviews From Moms In Our Collective

I‘ve been using this serum for eight weeks, and so far it feels like it’s the best hair loss treatment I’ve found. It smells sooo good and I like how it uses botanical ingredients. I was suffering from postpartum hair loss after my second child, and it feels like my hair is growing back fuller than ever.


I got so many compliments on how good my hair looked last night- not because I did anything different or fancy with it- only difference was using your product! #thankyou #goodhairclub


I am impressed with the instant volume I get every time I put it on.
