HAIR
Sara didn't think she could have

“When I received my cancer diagnosis, I didn’t think I had control over how much hair I lost. So I needed to take care of all of the things I could control tenderly. I did regular sauna sessions, cold plunges and scalp massages. I became more in tune with my health than ever, down to what I put on topically, but I didn’t want to lose the power over my outward appearance.”

RESILIENCE
Frances didn’t think she could have. 

As a model, my hair is very important to me. Pregnancy made me look closely at clean beauty. Postpartum, I noticed some hair loss and breakage around my hairline — I didn’t even want to tie it back. I thought that new motherhood meant saying goodbye to my old hair. I was anxious about it looking fuller again. Now, I’m relieved.”

STRENGTH
Jill didn't think she could have

“My gray hair, which I love, started to thin out when I hit menopause. I wanted to grow it long while still having it look healthy. It grew out thick and healthy until I hit menopause, when I noticed visible thinning. Now, when people tell me ‘I wish I had thick hair like you’ or ‘I wish I had healthy hair like you,’ I can’t help but think ‘Who are they talking about?!’”

PERFORMANCE
WanTing didn't think she could have

“As a long-time ballerina, I’ve worn a lot of tight hairstyles on stage, like a French updo or a ballet bun. It caused a lot of stress on my hair, especially around the hairline. Seeing results after a few months has made me more confident on and off the stage knowing that the product really works.”

CARE
Ashley didn't think she could have

“As a celebrity hairstylist, me and my clientele are always looking for clean, effective hair care. To do my best work requires a fully clean slate. With so many products leaving behind buildup or stripping hair entirely, I needed a solution that could effectively sweep away grime while soothing the sensitive scalp area.”

HAIR Sara didn't think she could have.

After receiving chemotherapy, Sara retained just 15–20% of her hair despite choosing to do cold-capping, a treatment which physically cools the scalp before, during, and after each treatment to help avoid hair loss. It’s no surprise then, that Sara felt she had no control of how much hair she’d be left with after chemotherapy.

Leaning into the idea of hair wellness, the same way she was with her self-care regimen (think a healthy diet, bespoke supplement routine, and regular exercise), she wanted to find hair products with ingredient names she could actually pronounce. Finding GRO Serum checked those boxes, helping Sara get her hair — and with it, a part of her identity — back.

RESILIENCE Frances didn't think she could have.

Becoming a mother can change everything — down to the hair on your head. While Frances was pregnant, she noticed her hair doubled in thickness. But postpartum, she started to see thinning around the hairline. While common, the hair loss made her feel less confident in her career and herself.

After using GRO Hair Serum for several months, Frances began to notice her hair felt and looked thicker at the top, which was where the hair loss primarily occurred. In turn, her hair made her feel more like herself again.

STRENGTH Jill didn’t think she could have.

As a model and an activist, Jill wanted to embrace her gray hair rather than dye it or hide it. Rather, she wanted to be able to grow a long, healthy head of gray hair — and not have to cut it short.

Fast-forward to menopause a few years later, and Jill noticed her hair was thinning, despite being an expert yogi and living a healthy lifestyle. After a few months of using GRO Hair Serum, her hair appeared visibly thicker and healthier, and was able to pull her hair back into the long and strong ponytail she envisioned. Jill also doubled down by adding the GRO Biotin Gummies to her hair wellness ritual for an inside-out approach to results.

PERFORMANCE WanTing didn't think she could have.

Being the Principal Dancer in a major dance company is no small feat. But front-and-center stage placement also comes with a lot of different hairstyles for different roles, with each one needing to be tightly pulled back. As a result, her strands were stressed and she began to notice hair loss and breakage around her hairline.

In the interest of aesthetics and her personal investment in the health of her hair, she began using GRO Hair Serum and after several months, saw visible results. WanTing then added the GRO Revitalizing Shampoo and Conditioner to amplify her hair wellness routine.
