After trying many hair masks and serums, this cysteine treatment finally controlled my frizz. The results lasted through several washes. It is formaldehyde-free, so I felt safe using it at home. The 480 ml kit is value for money. Packaging and delivery were both satisfactory.

The treatment does work and my hair is smoother, but the kit is a bit messy to apply alone. Also, I needed help for the back section. Results are good and it feels gentle, so I may buy again with someone's help.

Value for money. Used twice, hair is smooth and straight. No smell, no irritation. Comfortable on scalp. Delivery was fast. Recommended.

Nice product. Hair stays straight for weeks. No formaldehyde smell. Recommended for damaged hair.

Bought this for my wife, and she liked the results. I helped her apply it, and it was simple enough. No strong odor, and the hair did not feel stiff. The kit quality is good, and the price is reasonable compared to salon charges. Delivery was quicker than expected.

After reading many reviews I bought this. I have colored hair and was worried about damage. The cysteine treatment actually repaired my rough ends. The kit has everything, no extra products needed. Smell is zero, which I loved. My husband also used it on his short hair. It fits our budget because one kit lasts long. Hair feels light and manageable. Only thing is you need patience for application. Otherwise perfect.

Works exactly as described. My hair is soft, straight, and not damaged. No smell issue. Good buy for the price.

I was scared of hair treatments because an earlier one damaged my hair. This Beauty Tree cysteine kit is formaldehyde free and smell free, so I gave it a try. My hair felt smoother from first wash.

Very happy.

My hair was damaged from repeated coloring, so I was worried this treatment might make it worse. Surprisingly, it repaired the rough texture and reduced breakage. The process takes time, but the kit instructions are clear. After two weeks, hair still looks glossy. Delivery was quick, and the box was intact.

Works well but needs proper technique. I watched a video before using. Result was smooth and frizz reduced. One star less because the instructions could be clearer for first timers. Otherwise no harsh smell and scalp was comfortable.

Packaging was sealed properly and delivery reached in three days.
