For those of you having problems finding the right product, here are a few suggestions I have for you.
Dry, curly, or over processed hair:
I find Redken All Soft shampoo and conditioner are wonderful moisturizing products, great for the chemically dependent. Also Loma Simplicity shampoo and Intensity conditioner are a great combo for dry hair needing extra help. Peratin serum is a GREAT product, has strengthing properties,hydrates,and thermal protection. Love Love Love it!
Normal texture: Iso products work well keep color and provide conditioning without making hair limp.
Oily fine hair:
I suggest using only shampoo and a spray in conditioner. I tell clients to use Loma shampoo and Glide spray in conditioner. Awarness clenses the hair with out making it too dry feeling. Glide provides thermal protection and takes the tangles out without pulling your hair out by the root.
Hope this helps,
Lisa
