I just got a Deva cut and this was one of the issues I have had forever. She told me that frizz is because I am under moisturized. I really didnt think I could be since I do Dt all the time. She showed me to add my conditioner to soaking wet hair and scrunch it in like my stylers. I will even add some more water after I start scrunching it in. It has made a big difference. I do also feel that the cut itself has made a difference.
One thing I did learn that everything I thought my hair was it wasnt. I am not a wavy I am a curly and I am not high porous. I am fine/med when I thought I was course. I now know the proper products to use.
