Is this Sulfate Free, and does it lather. Does it give a 'clean' wash. Sometimes when a shampoo does not lather, your hair still feels dirty

In an answer to one person you say it's not suitable for color treated hair and then in another person's question you state it is for color treated hair. Not that I will believe you at this point but what is the truth?

HELP - Smoothing color-treated hair
I love the smoothing effect of this product. HOWEVER..... it removes the color (from hair dye) after washing my hair a few times. I wish that the company created a product which smoothed hair for those of us who colored our hair.

SO GOOD
This shampoo is phenomenal! Ive been using the green bottle for some tome and oove that one but wanted to try something else for a but. I went for a hair cut and the stylist used this on my hair and I fell in love with the way it made my hair feel, the smell was intoxicating and it reduced the frizz which is a huge PLUS for me especially since I have so much hair. I highly recommend thie product. You wont be sorry
Love this Shampoo

This Shampoo works great for frizzy hair. I have a lot of problems with frizz daily but after using Mega Sleek Shampoo it helped tame my frizzy hair. My hair looks healthier and actually isn't dull but full of shine and life!

Will always buy again. Leaves my hair feeling so smooth.
Great for daily use
I've been using thus shampoo for years because I have an oily scalp and want to wash my hair daily. This is the only shampoo and conditioner that my hair has never had to have a break from because it never builds up to weigh it down. My hair is baby fine but thick and I get it colored every 6 weeks. It has never caused dryness. I need to use the conditioner as well because my hair tangles easily. The conditioner is great but I also use a leave in detangler.
Absolutely not!
I tried this shampoo once my head was burning all day. Ok so I was like maybe it is what it is. Tried it again same thing. Had to return it! Try at your own risk ⛔️
