Anti frizz/curl cream?

[whs29]

I had a second transplant about 8 months ago and my hair started coming in quite fast, but frizzy with a big cowlick on one side of my hairline. Thus I read in a men's magazine that an anti curl lotion would help straighten this out. Subsequently I went out and bought some anti frizz/curl lotion at the nearest drug store and tried it out. The directions said to apply a small amount of the cream evenly to my hair and leave on for 5 minutes then blowdry. Well, I did as directed and it seems to have worked, but now I'm wondering if I should have done this because my scalp is now itchy, especially around the donar scar. I'm also wondering if the cream got into the scalp where the grafts were placed and could somehow have damaged those, even though it's been around 8 months since the procedure. I asked my stylist about this and he said you're not supposed to put it on your scalp, just your hair, but he doubts that any permanent damage could be done. Does anyone have any knowledge about this subject?
