I've been using this RARE OIL INTENSIVE HAIR MASQUE for over 2 year now - it works great! I have 24+ inch long hair that has blonde highlights, so my hair has been through the ringer. This Masque really helps my hair stay hydrated and smooth. I try to treat my hair 1 - 2x each month - I get best results when I leave the treatment in for 20+ minutes. I'd highly recommend, it is a bit pricey, but it is worth it to keep hair healthy. I pat on about four fingertips worth of products and let sit while wearing a shower cap, I rinse thoroughly with water after treating and use some leave-in-conditioner. This product is fabulous!
