Great for thin hair!

CustomerDecember 29, 2025

Very impressed! Pros: • Noticed hair growth with consistent use • Lightweight and not oily at all • Easy to apply—no mess • Smells great, clean and fresh Cons: • Results take a little time (but worth it) This serum is perfect for fine hair. It doesn’t weigh hair down and layers well with styling products. Hair feels healthier and looks fuller over time. I’ll definitely keep using it! Read more

Slowly but surely works!!!

CustomerDecember 9, 2025

I've been using this product for 2 months & it works! Slowly my hair has gotten much thicker, I'm hopeful that the length will get longer soon. I've gone through serious hair thinning this year to where i had to purchase a hair topper. Im extremely happy with my results! Read more

Not Magic, just an effective product that works.

Moving to WoodstockNovember 12, 2025

This works. Is it magic? No. However, if you follow the recommendations for use and consistently use the product. You will see growth. I am pleased with the results. During menopause, my hair thinned horribly. Panic was setting in and my hairstylist told me to try the shampoo and serum. I was happy with no harsh meds (minoxidil) and no way to ever stop using said meds. Is it expensive? A little, but nothing like the programs and products that cost hundreds of dollars a month. The serum does not make hair oily, nor does it dry the hair out. I am more happy with my hair than I have been in a while. Read more

Saving Grace!

MTAugust 29, 2025

I have used this for two separate postpartum experiences. First time I had extreme shedding at 6 months and my hairdresser recommended it and it helped slow it down and regrow my hair. Second time I started using it right after giving birth and I had ZERO hair shed. It’s been incredible my hair has a tendency to thin out around my hair line and it’s kept it full. I recommended it to a family member too who had hair loss due to UC and it significantly helped them too. Scent is nice and light. Water consistency that absorbs so quickly so it doesn’t make hair gross with daily use. I used mine only a few times a week when babies were young and it still worked great. Read more
