Hey there! 

My hair is thin and curly naturally, with low porosity and good elasticity. The scalp is typically normal to light oil.

My hair tends to be frizzy, dry, brittle, with split ends. The biggest change I can make to my routine is to use less heat, and use a hair care line based around smoothing. Another thing that would help is limiting chemical treatments such as the Keratin treatment I do every 6 weeks and coloring my hair every 4 weeks.
