What shampoo do you recommend for dry frizzy colored hair?

Biolage makes a great Hydratherapie masque. It takes about 5 minutes.

Brocato. It's expensive but well worth it.

John Frieda frizease line.

I just did this on my hair 1/4c mayo 1 whole egg, drizzle of olive oil. Mix it all and slater on your hair. Wrap your hair in saran wrap then in a towel to sit around for 30 minutes. Rinse with COLD water or you will cook the egg, I recomend shampooing twice to get rid of the mayo smell then let your hair air dry. It keeps my hair smooth and frizz free for a week.
I use John Freida's frizz ease line, I have the deep conditioner, the frizz serum for wet hair, the frizz ease styling gel and hair spray. Even if I use them all together it doesn't help. It couldjust be my hair though.

My hair isn't colored, but I use Suave Keratin. Its cheap and it makes my hair so shiny and soft. I'd recommend it to anyone.

Redken color extend worked great for my hair.

Have you tried co-shampooing, I think it's called? It's just using conditioner to wash. I've had good results with doing that when my hair gets bad.

if you want to do it the cheap way just wash your hair briefly (wash after 30 seconds or 1 minute) and if you have split ends dont apply shampoo to the bottom (soap will naturally go there just in small amounts)
then condition your hair and turn the shower off, leave it in your hair for one hour or so
unless i have magical hair, ive noticed it doesnt matter the brand too much when you are going cheap because this technique is a deep condition that only needs to be done once a month or so (for me at least)

if you want to spend money though and put in little effort go for paul michelle its amazing
OR Great Clips brand name set made by them (forget the name)
im in Cali though don't know if you have a Great Clips.
GL!
