I've never tried beer, does it work?
I've tried Sunsilk Silky & Straight, it's really nice, leaves my hair really smooth and silky feeling. Also Herbal Essence for Coloured/Highlighted Hair and Avon Naturals Strawberry and Guava Shampoo and Conditioner.
I've also used some serums that have worked. Sunsilk Silky & Straight Serum and Avon Celloshine Treatment.
I'm currently using the Avon products, they're great.
If you straighten your hair or blowdry it you might want to try Schwartzkopf Gliss Hair Repair Shine Tonic. Schwartzkopf Gliss Masque is also really nice.
