Professional Colour Lock Midopla Mask By Bes Beauty & Science with Natural Keratin 35.2 FL OZ

Great product! I leave it in my hair overnight or for a couple of hours before rinsing it. It leaves my hair soft and healthy looking.

The second time bought this mask in general, the first time on amazon. My hairstylist recommended it and it is 100% worth it! Hair doesn't turn yellow over time. I like it definetely
