I have very thin AND very fine hair due to a thyroid disease when I was 18 years old. I am in my thirties and was almost embarrassed by the fact that my hair is so thin. I read reviews about Voloom and just decided to take a chance. Just to be clear, it will cause frizzy looking hair, I mean come on, it is just like a crimper (which ALWAYS cause frizzy looking hair). But the volume is fantastic for someone like me who has limp, fine, thin hair. I don't always wear my hair down after using the Voloom so the added body even for a ponytail is unreal! Maybe it's just because I have dreamed of volume in my hair since I lost it to a disease, or maybe it's just because I don't expect "miracles" from Voloom, but I love what it does for my hair. I just can't say enough about the fact that it will make it frizzy, but there are products to help with that.
Bottom Line: Yes, I would recommend this to a friend
