Product is really great. I’ve used 100’s of products in my 47 years and this is top 5. Helps the hair remain bright and shiny especially if you have color or highlights also keeps it healthy. my only complaint is the bottle is way way WAY to SMALL!!!! I have long very thick hair and I can only get 3 to 4 uses out of one bottle. I took one star off that. I don’t know if I’ll continue to use it….just based on cost versus amount. It’s just not cost-effective for me. However, if they come out with a larger bottle, I’m 100%. all in and a customer for life. If the small bottle is not an issue for you, I said go for it. I highly recommend the product.
