Anything I used to apply to my scalp caused irritation, from conditioners to oils to tea spritzes. There'd be redness and itching and I'm sure I tore my hair out just to get some relief. I've used sulfur, essential oils and even otc ointments to try and calm the inflammation. At one point just gave up and went to a derm (who couldn't really find anything).
The first few months of putting nothing on my scalp without having to worry about my hair strands were bliss. I mean, they itched for the first few weeks because my scalp was tender from the installation. But by month 3, I'd been having no itching nor irritation for 2 solid months. I decided to use tea sprays (because I really did love how they made my loose strands feel) but only right before wash days. Now I can use them multiple times a week without even mild itching.
Wow, it seems a lot more dire written out like that, but it mostly seemed like a mild nuisance while I was going through it. I did overnight treatments knowing it would cause about a week of irritation and thought it fair trade. I mean, I am grateful I got all the loose hair experimenting out of my system. I don't think I could have locced any earlier since I kind of figured I'd have to bite the bullet eventually to get some peace. (Knowing all this I'm still annoyed that my hair refuses to grow 2" a month, or loc fully in 7 months flat or won't magically turn whatever colour suits my fancy atm
)
Oh! I also chose sisterlocs over traditional because the thought of gel being on my scalp even once a month made my whole body itch. So I feel pretty settled in my decision for locs tbh. Scalp happiness alone.
