My hair is over processed, and I have used many chemicals over it in last 5 years now. I started coloring my hair when I was 15, and then hair straightening, excessive use of flat iron, and what not! Eventually, my then healthy hair, have become fine and thin now. After doing some research, I decided for 2 brands, namely, Mega tek and Ovation hair therepy, but the reviews have confused me. I donât want to shell out exorbitant amount of money, to only repent later on. I want to know from some hair expert whether which of the two you found the most suitable for fine and thin hair as mine! Please suggest! Thanks.
