This stuff is ammmazzing for natural curly - natural frizzy - natural crazy insane hair like I have! I've been using this Frizz Ease serum by John Fredia since I was about 13 years old! Right after washing hair, I just use a tiny small amount to wet hair. Do not wash out! It really helps the frizz!! John Fredia is amazing!! A very little goes along way! So be careful not to use more than a tiny amount or you will have that oily look! Great stuff!
