Review on Biotin Shampoo and Conditioner: Effective Hair Growth Treatment for Men and Women - Boosting Volume, Thicker Hair, and Blocking Hair Loss by Danielle Jones

The previous version of this brand was great. You can find it if you search, but it's not available. They then doubled the price even though they had the same ingredients in the same order. They just poured it into another bottle. I stupidly bought the more expensive version and was able to check if they are the same. Now they've added caffeine and raised the price again. But this conditioner is different - it has an unpleasant citrus smell. I still have the previous version and the smell is much better and cleaner.
