Query: This stuff works!

I'm a 52 y/o woman who's had problems with hair loss for over 20 years, trying everything from minoxodil to OTC vitamins, minerals etc. Of course, I approached this with the same skepticism I've had about other products. After the first 3 months, there was noticeable hair growth. I saw hair growing where there previously had been nothing but scalp for years. Read the ingredients, read their theory and philosophy on how hair loss occurs and read other product ingredients--and it just makes sense. There's more than one way to get DHT out of the follicles and this is the safest, most natural and healthy way to do it. I just wish they'd offer a better price for larger amounts of product, as this package will only last you a month. Try it for 3 months - this stuff will never harm your scalp and if you follow it, I believe you'll see success.
