Bad Hair Product Ingredients

TennsTenns Posts: 40Registered Users
Can someone let me know of some of the top worst ingredients in hair products. Ingredients that could be harmful, smothering, etc. to hair. I'm looking to purchase new products to use on my hair, but I do not want products that contain harmful and/or useless ingredients.

Also, could some please tell me what ingredients are good for the hair that I should look for in hair products.

Thanx a bunch!!! :D
