I have been using the spray for one month now after feeling my hair thinner with less volume, and I can already see a lot of hair growth. Can't wait to see the results after 3 months of use. I have never seen that before. My hair are thicker and looks way more healthy. I am really happy with this purchase and knowing that the formula is clean, and made with natural ingredient it's even better! Also, it is ultra-light so it doesn't grease at all. Strongly recommended.
