So my hair is pretty thin. (not thinING thankfully, just thin) Is there any way to make it look thicker? (or make it actually thicker, but I'm guessing the answer to both of these questions is no and you have to deal with what genetics gave you)
You mean fine in texture? My hair is fine, too, and I like it. I'm not going for terminal length or anything super long, so I think it's better that I have finer hair. I don't think you can do anything about it, though.
Do you have a pic of your hair?
You can buy volumizing shampoo and conditioner. While it doesn't make a huge difference, you will see some more volume/ thickness in your hair. It's not a permanent thing, but it doesn't harm the hair and makes it appear thicker.
