what causes the hair to look frizzy
Lack of moisture and protien may also cause hair to frizz no matter WHAT product you're using. This is why hair can frizz when it gets humid outside. Humidity is moisture in the air. Dry hair will absorb the moisture and expand, causing FRZZ.
There are several factors that contribute to frizzy, fuzzy, or furry hair. The outer layer of hair, or cuticle layer, needs to lie flat to maintain a smooth appearance. Rubbing your hair with a towel to dry it could rough up this layer of hair and make it appear frizzy.
