    This stuff works!

    My entire life, I’ve had full thick hair, but was so distraught when my hair started falling out after a 90 lb weight loss (not on glp-1). I decided to try this product and loved the formula. Not oily or sticky at all. I was extremely consistent and used it every single night and also washed my hair 1 extra time during the week because I heard that helps. Those were the only 2 things I did and it helped so much! After 3 months of use my hair is noticeably more dense and my hair stopped falling out in clumps. Super happy and thankful for this product!

    I really liked the product, but it’s out of my budget for now. I wasn’t able to use it long enough to see results so i can’t give a real review.

    Love it

    I have been using this serum for just over a month and absolutely love it. I started using it when I began having more shedding than usual. It is definitely helping with the shedding, it does not irritate my sensitive scalp as other scalp serums do, and it does not weigh down my fine hair at all. This will be a new staple in my daily hair routine and I will continue to purchase!

    Only been a week but can honestly say relief crept im from day one - scallp had been feeling tight and itchy without flakes for about a year . This is the third product of its type ive tried and no satisfaction from the other 2 brands . Also , no overlap in usage . Has been over 3 months since touched the others . So, I am positive the progress is from this . Yes , its pricey compared to a majority of the others but I believe its a case of “ you get what you pay for”
