Where I’m from, some scholars say hair extensions are allowed so long as it’s not human hair or looks like your hair e.g horse hair so things like wool,Brazilian wool or thread are allowed.Some say it is allowed so long as it doesn’t exceed your natural hair length and others say It’s completely prohibited. A lot of us braid as protective styling. Please clarify.
If it’s wool or ribbon and it doesn’t look like hair at all and everyone can say that this does not look like hair at all, in this case this is permissible. However, if it resembles hair in any form then this is absolutely prohibited and one of the major sins in Islam, whether it’s made of real hair or any other artificial fibers.
