Product is genuinely nice. Used it on my sister's hair, smooth and straight ho gaya without any burning smell. Slightly pricey but one bottle goes a long way, so worth it. Recommended.

Ordered this after my regular salon quoted a very high amount for cysteine treatment. Applied it at home with my sister's help, followed the instructions properly and the result was actually good. Hair feels soft and easy to manage, frizz is under control even in this humid weather. No chemical smell at all which is a big plus for me. Will buy again once this bottle gets over.

I ordered this after reading about cysteine being gentler than formaldehyde treatments. My hair is wavy and frizzy, and I wanted something for family functions. The application took time because I have long hair, but the results were worth it. My hair felt salon smooth, and the smell was almost nothing. It did not make my hair stick straight, but it reduced the puffiness a lot. I like that it is formaldehyde free and safe for home use. The 120 ml bottle lasted me three uses. I will recommend it to my friends.

I have short hair and usually avoid hair treatments because they feel greasy. This one is different. It rinses out clean, and my hair does not feel weighed down. I used it on a weekend, and by Monday it was still manageable. The gloves and comb in the box were helpful. Comfortable to apply, and no burning sensation on the scalp. Good for regular use if you follow the timing.

Nice product for men too. I used it mainly for my hair, and it remains neat after washing. No irritation and no heavy perfume. The 120 ml quantity is sufficient for medium-length hair.

Very good product. My hair feels soft and straight after one use. No smell, no irritation. I was worried it would damage my hair, but it actually made it smoother. Will buy again.

After one use, my hair fall during combing reduced because there were fewer tangles. The cysteine and amino acid mix feels gentle. It gave a natural straight look, not poker straight. Worth trying for damaged hair.

Living in Chennai, humidity usually makes my hair puff up within minutes. After using this treatment, I noticed a clear difference. My hair stayed smooth even on a rainy day. It does not have that awful chemical smell, and my scalp did not feel itchy. I used it once a week for a month. The results are not permanent, but they last long enough to make it worth the price.

I have short, frizzy hair and this worked better than expected. The application process takes time, but the result is smooth and salon-like. It did not dry out my scalp. Delivery was on time and packaging was intact.

My hair was brittle from a previous straightening treatment, and I needed something repair-focused. This product has acai oil and marula oil, which I think helped with the dryness. I used it as directed and left it on for the full time. The result was not poker straight like a salon rebonding, but it was smooth, soft, and much easier to comb. I have reduced my daily usage of a flat iron because the frizz is under control. The smell-free formula is a big plus for me. I will repurchase.

The product quality is impressive for an at-home treatment. It tamed my flyaways and made my hair shiny. I used it on my sister too, and she also liked the result. Only wish the bottle was bigger.

I have been using this Cysteine Plus treatment for close to two months and the difference is clearly visible. My hair used to get very frizzy and rough at the ends after every wash, but now it stays smooth for almost a week. The best part is there is no harsh chemical smell, unlike the straightening products I tried earlier. My wife used it once as well and she was satisfied with the finish. If you compare with salon charges, this 120 ml bottle is definitely value for money because it lasted me three sittings. Recommending it to anyone dealing with damaged and unmanageable hair.

Simple and effective. No formaldehyde smell, no itching, and my hair stays straight for weeks. I use it once every ten days. Good for men who want less frizz without a complicated routine.

Simple to use at home if you watch a tutorial first. I liked that it is formaldehyde-free and does not leave that typical salon smell. My curls loosened nicely without looking flat.

I have spent thousands on salon smoothening, so I was skeptical about doing it at home. This kit changed my mind. The 120 ml bottle is enough for my shoulder-length hair, and the application is not messy if you section the hair. It feels comfortable while sitting with the treatment on. After rinsing, my hair was straight and shiny without that artificial flat look. It fits my monthly budget much better than a salon visit.

My hair was damaged from repeated coloring. After using this treatment, the roughness has reduced a lot. It is not a permanent straightener, but the smoothness stays for weeks. Packaging was neat and leak-proof.

Works well for frizz and gives a smooth finish, but you must be careful with the quantity. I used too much on my first try and my hair felt a bit dry for two days. On the second attempt, I used less and the result was much better. No smell, no burning, and it did not irritate my scalp. Good product overall, just follow the instructions properly.

Bought for my husband and me. Both of us have different hair types, yet this worked well. No burning on scalp and no strong odour. The serum-like texture spreads easily. Amazon delivery reached a day early, which was a bonus.

Effect is nice and hair looks straighter for almost three weeks. I have thick wavy hair, so I needed a little more product. The smell-free claim is mostly true, but there is a mild chemical note during application. Still a decent buy.

Bought this for my damaged hair after years of coloring. The cysteine and amino acid mix sounded promising, and it did not disappoint. I use it once a week, and my ends feel softer instead of rough. The best part is there is no chemical smell, so I can do it on a Sunday evening without getting a headache. It fits into my routine easily. My hair is more manageable now, and I need less serum. I have already recommended it to my sister.

I was tired of salon straightening treatments that left a strong smell and burned my scalp. This Beauty Tree cysteine treatment is a different experience. I applied it after a clarifying wash, kept it for the recommended time, and the result was genuinely smooth without any harsh fumes. My wife helped me with the back section, and it felt comfortable on the scalp. After three washes, my hair still looks straight and frizz is much less. I have thick wavy hair, so I did not expect salon-level results at home, but this came close. Worth trying for anyone worried about formaldehyde.

Used it after reading about formaldehyde-free options. My hair feels softer and manageable, though you need to follow the instructions patiently. The acai and marula oils seem to help with dryness. Good quality for the price.

I was hesitant to try hair straightening at home, but this cysteine treatment surprised me. The 120 ml bottle lasted for two sittings on my shoulder-length hair. It did not smell harsh like salon products, and my frizz reduced from the first wash. Delivery was quick, and the box packaging was sealed properly.

Strengthened my brittle hair and reduced breakage drastically.

Nourishes the strands while providing long-lasting smoothness.

Straightens hair gently without chemical harshness.

My waves are more defined and frizz-free now.

The blend of Acai and Marula oils gives a luxurious finish.
