How many celebrities do you know wear hairlocs. I have very thin hair, and some friends recommended I get hairlocs to at least thicken it a bit. Do you think it changes your look completely? I know that hairlocs are used worldwide. But what I want to know is what ways there are to get hairloc or hair extensions into the hair? The longest running hairlocs are those which are sown, and thatâs it something I want an opinion about, if it should be done?
