This formula does work and I have tried it on myself after I suffered from an awful experience at the beauticians. I went to get the High Definition Brow treatment with high hopes. The amateur beautician ended up messing my eyebrows. I was left with a very gothic looking dark black tint on my eyebrows and over-plucked eyebrows underneath it. My natural eyebrow shape had been lost. As a person's Eyebrows have a huge impact on ones appearance. I had the added embarassment that my nose now appeared very big/fat as my eyebrows appeared too harsh and were missing alot of hair immediately above from the inner corner of my eye. Dis-heartened and desperate to get my eyebrows back to normal quickly I formulated Super Eyebrow Hair Growth Booster which I used on myself. It took a few days to notice the first spurts of growth and within a few weeks I had progressive growth which then lead to full growth and better coverage. My eyebrows look the best they ever have.
