I am using a hair straightener for last 4 months now, and I bought it from a local store! Since my hair is extremely frizzy and curly, I wanted to know whether a tigi hair shampoo would be better to keep my hair straight rather than using a heat product on my hair! I have read in various reviews that Tigi hair products are quite effective in making hair silky smooth and shiny. However, the price seems to be quite exorbitant, and this is why I am a bit apprehensive about buying Tigi hair products! Can some hair expert please advice, if there is an affordable replacement to Tigi hair products, but with the similar quality? Please help me with some suitable suggestions.
