Honestly, I didn't have high hopes for the Fazax product; I bought it because I was swayed by the numerous enthusiastic reviews from my mom, who uses this product. I didn't expect that Fazax would help me grow my eyebrows – they used to be less thick, and I had to "fill in" the sparse areas. I remember applying pencil with a shudder. The pencil looked very unnatural and easily smudged on my skin if I touched it. But now I have thick, dark eyebrows, and I've tossed the pencil into a drawer, hoping I won't need it again. It's definitely a good product. It helps to grow natural eyebrows and keeps them in good condition. The 20 ml in the bottle is enough for a 4-month course. I give it 5 stars.
