Protein Coditioner question?

I use organic products on my hair namely, natures gate tea tree shampoo and pomengrante conditioner. At gnc there is a shampoo and conditioner that has hydrolized keratin in it, there is no chemical in it , the one thats long and starts with f, sorry cant rember it. Its organic, will this be dangerous to use on my hair, or should i just use egg yolk to strengthen my hair?
