Amazing
My hair feels so soft and hydrating after using this and I have tried many conditioning heat protectants and this is so far the best one how it makes my hair look and feel. I have dry bleach blonde hair so it helps a lot

It serves its purpose
This definitely protects the hair and leaves it looking smooth and healthy. However, if you have fine hair, DO NOT use much. A light mist is more than enough. It smells weird and chemical ish, but it disappears when your hair is dry. Not my holy grail, but it’s ok to protect from heat damage
