So I have very weird hair. It was poker straight as a child, started going curly as a teenager then started going straight in my 30s again. It’s now straight underneath but top layer has a natural wave (with tendency to frizz). I usually dry it smooth but want to sometimes diffuse it curly style like I used to. When I was younger I would put mousse on it then diffuse it, but if I use that now it tends to go straggly/crispy in parts (sounds attractive hey!). Anyone got any tips for products/Methods etc. Thanks
