I am 59 years old and recently found my hair thinning in the crown area . I am so pleased to see results this early on . I am on my second month and can see my thinning spots starting to fill in and I see less hair going down the drain when I wash my hair . I use the shampoo , serum , capsule supplement and marine collagen. I can’t wait to see the results as I keep using these products . I think consistency is key and I don’t miss a day using the products . I highly recommend!
