When I was 19, I went to cosmetology school and got my first perm in my life. My hair was down to my waste and things went terribly wrong. I had an allergic reaction and my hair came out in handfuls. Other than having to be a beauty school dropout, my hair was a wreck! My mother is into natural herbs. She researched and found out that Horsetail is a natural herb that helps your hair, skin, and nails. Alta Silica is the active ingredient in Horsetail. I went to the local herb store and asked for Alta Silica. I bought it (I think it was less than $30) and took 3 pills per day. My hair grew 4 inches in one month and my nails and hair never looked better!
A few years later, I was working with a woman with very thin hair. She'd tried everything. I told her about Alta Silica. She took 3 pills per day and in no time, her hair was thick where you couldn't see her scalp through her hair on the top of her head.
Now, years later, my husband's hair is thinning. I purchased Alta Silica and it's working on him, too!
Word of caution, you will have to shave or wax hair in other areas more often and I did notice my eyebrows needed tweezing more often but it was worth it! Don't know if it will work on eye lashes, but can't see why not.
