I have - or HAD - really full, thick hair. It looks thick now because most people don't really comprehend what mixed race hair is like, and assume because it's fluffy, it's thick and healthy. My hair is anything but that; when I braid it now, i want to cry at how thin the braids are. I've been wondering whether or not to just cut it all off and deal with it, or wear a wig. I don't dare to weaves or braid-ins, because the weight of the hair and the twisting makes my hair so brittle it would probably break off more than it does now. My hair is finally growing again (it didn't grow for about 6+ years) thanks to taking brazil nuts daily - yay, selenium! - but it's still very thin on top and just not as full as I'd like.
I decided to try giving some clip-in hair extensions a try for going out; there's no extensive, exhaustive process for it, they're relatively cheap, and I was able to match my hair colour and texture pretty well. Being a diva, I got the longest length I could find, and put them in when I went out on a date earlier this week.
I love them. I adore them. I'd do a half hour infomercial for clip-in hair. I couldn't believe it when I looked in the mirror - it was my old Me looking back. I bought two packs because when a sistah wants full hair, she wants FULL HAIR and I wasn't messing around. My hair was a MANE, and with these clip-ins, that's what I got. I'll post some photos at some point, but I loved it.
Seriously, if you're having issues with thin hair, and it's bashing your self-confidence a bit, do yourself a favour and give these things a try.
