The 900 ml bottle is great value. My hair is thick and frizzy, but after this treatment it is much smoother. The parcel reached fast and the product was sealed. Only thing is you need someone to apply it properly.

Paid much less than salon charges for one treatment. Used it at home with my cousin's help. The result lasted well for weeks. Packing was solid, no leakage at all.

I was looking for a formaldehyde-free option because I have allergies. This one suited me well. No sneezing or itching during application. The 900 ml bottle is enough for many uses, and the consistency is easy to work with. My hair feels salon smooth and has a natural shine. I use it twice a month and it fits into my schedule easily.

I was scared of keratin treatments because of harsh chemicals. This one is formaldehyde free and smell free. My hair feels straight but not completely flat. Will repurchase for sure.

It works, but you cannot expect magic in one sitting. I have wavy hair and it made my hair straighter and smoother after three uses. The smell is not an issue and it did not damage my scalp. However, the effect reduces after a few washes, so you need to repeat it. For the price, it is decent, but not exactly salon level.

Bought this for my salon. Clients are happy with the finish. It does not have that irritating smell, so it works well for sensitive customers. Shipping was on schedule.

Nice product. My sister used it first and then I ordered. Hair is soft, straight, and there was no irritation on my scalp. Works well if you follow the instructions.

I have been struggling with frizz and flyaways every morning. This treatment has made my daily hair routine much easier. I apply it as directed once a week, and my hair remains smooth and tangle-free through the day. The cysteine and keratin combination feels gentle, and my colored hair did not fade. It is comfortable to use and does not leave any heavy coating.

Superb product. Hair became silky and manageable. My stylist used it and said the quality is good. The 900 ml bottle is enough for multiple sittings.

Decent hair treatment. Straightening effect is good but I expected a bit more shine. The courier was quick and packaging was fine. For the price, it is okay.

The bottle is huge and will easily last six months for two people. It spreads nicely and does not drip much. The smell is very mild, almost like nothing. My hair feels softer and straighter after two uses. No sticky residue. Good buy for the price.

I have frizzy wavy hair and this cysteine treatment worked better than expected. No formaldehyde smell at all. After two washes it is still straight and soft. Packaging looked neat and the parcel came a day early.

Good quality cysteine keratin. The smell is mild, not overpowering. Hair feels salon smooth after blow dry. Dispatch took three days but the packing was intact.

Bought this 900 ml pack for my wife and me. We both have thick frizzy hair, and salon treatments were burning a hole in our pocket. This cysteine keratin treatment gives almost salon-like straightness at home. You need to follow the steps patiently, but the results last well. I use it every Sunday and my hair stays smooth for the week. Great value for the quantity.

Ordered this for my wife after our salon quoted a high price. Courier arrived quickly and the box came sealed properly. Used it once and her hair feels smooth without any harsh chemical smell. Quality looks salon grade.

I have a sensitive scalp and was worried about using any keratin treatment at home. This Beauty Tree product is genuinely formaldehyde free and has no harsh smell. The application was comfortable, and the cap fit my head well without slipping. My hair felt smooth and manageable from the first use, and I did not face any itching or burning. It has become a weekly ritual for me.
