Great product - easy to use!
Really gives volume to fine thinning hair without stickiness
This comb smells amazing and helps keep my frizz under control. The teeth are slightly narrow so if you have thick hair I would suggest a wider tooth
Great service order arrived promptly
I really love this Verbena Shampoo and conditioner. I have a few other Angel shampoos which are lovely but the Verbena is helping a scalp condition caused by a medication I was on and it is not too drying. I will be buying the larger size. Thank you!
Great colour very vibrant on bleached hair, easy application
I placed my order on Wednesday afternoon, and it arrived by Friday morning. Very fast and reliable service! I’m really happy with my experience and will definitely order from them again in the future.
