a semi permanent made my hair feel dry and definitely straighter. I applied it to fresh growth hair with a small amount of previously dyed ends. I went darker than my natural colour.

I've tried many different dyes over the years, usually having to completely cut out the dyed parts after a few years (my hair is fine, and at some point will no longer hold the darker dye). I have yet to try one that made my hair feel nice to the touch, tho some seem worse at sometimes than others.

I keep eyeing the henna option but the thought of cutting it out after taking so long to grow out from a pixie is a bit overwhelming.

3a? 3b? Fine, dense. Porous.
Finally sulfate free. Avoiding silicones.
