Here is a list of what's helping my edges to get thicker:
1. Tying Satin scarf in different places every night (So that the knot isn't rubbing against the same spots around my hairline all of the time)
2. Making sure satin scarf or bonnet is tied near eyebrows and below hairline (so that it's not rubbing against hairline)
3. Massaging my scalp especially around the hairline with Kera Care essential oils for the hair (I do this about once a week and don't use too much, a little goes a very long way
this seems to be really growing the hair around my hairline
4. Wearing very loose ponytails and buns tied with a piece of satin fabric instead of an elastic band
5. Making sure roller sets are not too tight (actually my stylist does this)
6. Eating healthier (lots of veggies, fruit, lean meat,chicken, and fish,) and drinking a lot of water every day has made all of my hair grow a lot faster
I'm sure your edges will start growing back thicker soon
