I was part of the "Wen" haircare settlement; after using "Wen", my hair began to fall out in handfuls. Being as my hair was baby fine to begin with, the result was very unattractive....after trying supplements, red laser hats, which are very expensive, various shampoo & rinse products & a variety of topical additives, I'm super happy to report that Actsyl is the first & only product that has delivered on its promises! With the first bottle I noticed a marked difference in the volume of my hair....I'm on my second bottle & I almost look like my old self! I can't wait to see what the future brings! Thank you, thank you, thank you Actsyl!
