I have been trying to find a way to naturally stimulate hair growth; over the past 3 years it's stopped growing passed my shoulders and so I was very excited about this product! Maybe I didn't use enough, but I followed the directions and put the product in sections of my hair but I don't feel like it's grown at all in 3.5 months and it still looks extremely thin on the top (where I've applied the most product). Unfortunately, this didn't work for me so my search continues. On a positive note, I have an extremely sensitive scalp and this product didn't cause any irritation and it did help me with reducing how much hair I was shedding. The first 2 videos I took 7/2/22 (I forgot to take a before picture), the 3rd and 4th pictures are from 8/26/22, and the last 2 were taken today (9/27/22).
