I ´Ve been using these gums for a month now, in combination with growth serum. I really see a difference. My natural brownish colour is very dull, hair is lifeless and so thin that when in poney tail, it looks more like a rat’s tail. After consistent use of these gummies, in combination with Pita shampoo, conditioner and serum, my hair looks healthier, stronger, I even have a bit of volume which honestly has never happened before. And the major difference is in the color, it’s brighter, shinier, looks pretty. Although it’s not a panacea and I will never have the kind of hair they do advertising with, I’m still very happy with the result. If I put only 4 stars, it’s because of the taste which is god awful. I always have a glass of water to wash it down, otherwise I think I would vomit. Maybe it’s personal distance as other people in comments do not mention such a strong « distaste ». Anyway, seeing the results, it’s still worth it
