Henna brows review: I (mostly) always get my brows tinted and waxed at glamour garage and love the results every time. This time I thought I’d try henna brows as I heard they lasted for 8 weeks so thought great I won’t have to shape them for a longer amount of time. Initially they were a little bit patchy on the edges so day 1 I had to fill them in (which defeated the point). Over the next few days ALL the henna colouring went patchy and by a week in it had totally gone where I was left, really, with just tinted brows. At the appointment they said being in the sun or on sun beds would make them fade quicker where I hadn’t done either so just didn’t work for me. I would stick with just getting them tinted and shaped in future.
