How do I make my hair very soft?

Soft hair starts with healthy hair use a sulfate free shampoo and protein rich conditioner like Paul Mitchell's Awapuhi Wild Ginger Line you can even search local salons to see if they offer the Keratriplex Treatment from the line it repairs the internal structure of your hair rather than repairing surface damage like most conditioner and "deep" conditioners do. 

Use a good shampoo & conditioner, concentrate the conditioner on the ends. Don't over-rinse the conditioner out either. your hair should feel silky when wet.

Hi. Filipino here. I use a shampoo called Avalon Organics "thickening" shampoo and it claims 70% organic and sulfate free (sls/sles, paraben-free. Or so it claims) It's from the U.S. I buy this from a mall shop called Healthy Options. Do you think this shampoo is good enough? I don't have much choice since there is only very limited hair care products available here. Almost everything here is commercial(proctor and gamble products, loreal, pantene etc.) and therefore uses lot's of chemicals. I'm really trying to take care of my hair especially my hairline and that's why I use clip in hair to protect my own own hair from excessive styling. Have anyone here tried the brand that I'm currently using?

Apply the mixture of Castor Oil and Coconut Oil taking equal quantities of both, let the mixture be in your hairs over night, wash your hairs in the morning using mild shampoo. Try it at least twice a week or thrice a week. 

Use GK the best. Only one wash will make your hair smooth & soft for up to 5 months. A little bit an expensive one but your hair deserve it. I use it for years and I am quite satisfied with the results. I found a good shade for my hair which I yearned for. I will recommend it for anyone who wants straight, smooth & soft hair that lasts long and in style.
