Shake before use!
"First time using this and all I got was gel, then a rush of liquid (which went everywhere). Lesson learned and I now shake before use! It is runny though and I’d suggest either making it thicker or including a pump dispenser. I did manage to re-purpose one though, from my stash of plastic items I couldn’t bear to throw away! I find it does need a second shampoo sometimes, depending how dirty my hair is. Love the metal bottle and a good product within!"
