I was sceptical....I have fine, foiled 2b/C hair that I have struggled to refresh since I started my wavy journey 1.5yrs ago..I will also add that I protect my waves at night...but I am a restless sleeper...Water just makes it frizz and nothing seemed to work...Then I came across this...I was sceptical of using a serum...and had visions of an oily mess...Well...I was wrong...This product is weightless and small amount just smoothed through sections springs it back to life without frizz...I can now get at least 3 days between washes, which was unheard of before...So happy.
