I ordered for my wife and she is happy with the results. Her hair feels smooth and looks straight without any salon appointment. The bottle is big, so it will last long. Delivery boy handed it over carefully. Good purchase.

Nice product. Used once, hair is straight and soft. Takes patience. Quantity is huge. No irritation. Good for men with frizz.

My hair is wavy and thick. I wanted something to reduce volume without making it flat. This treatment worked nicely. Hair is smooth, shiny, and feels softer. The no-smell formula is true. I could comfortably sit through the process. I use sulfate-free shampoo now and the effect is lasting. Recommended for anyone tired of salon bills.

Good product overall. Hair became smooth and straight after one use, and there was no strong chemical smell. I gave 4 stars because the process takes time and the instructions could be clearer for beginners. Still, it is worth the money if you want to avoid salon visits every few months.

The product works, but it is not completely smell-free. There is a faint chemical scent during application, though it fades after washing. My hair became soft and straight, and the frizz reduced. I took one star off because the pump bottle was hard to press, and a little product got wasted. Delivery was fast, and the kit arrived in good condition. Still a decent option for the price.

Ordered for my salon at home setup. I have used many keratin and cysteine products; this one is surprisingly good for the price. The cream spreads easily and does not dry too fast. It gave a natural straight finish and reduced frizz. Clients with sensitive scalp did not complain about burning. The 1600 ml size is practical for repeated use. Only thing is you must buy a flat iron that reaches proper temperature. Overall, a solid formaldehyde-free option.

Packaging was solid, no spillage. Used once, hair is smooth and shiny. Mild fragrance. Will update after a month.

Works well if you follow timing. My hair is smoother and easier to comb daily. Slight straightening, not poker straight, which I prefer. No smell issue.

I have thick wavy hair and have tried many at-home kits. This one was surprisingly gentle because it is formaldehyde free and almost smell free. The cream is thick and spreads well, and the 1600 ml quantity is generous. I used it with a friend and we still have some left. Results lasted around six weeks with sulphate-free shampoo. It made my hair smooth and shiny, though you must follow the timing exactly. For the price, I will definitely purchase this again.

Used it twice on my sister and myself. First time we followed the timing exactly, and the result was salon smooth. Second time we left it a bit longer on my thick hair, and it became even straighter. No burning or itching. The neutralizer did its job. Delivery was on time and the package came with all tools. Very satisfied.

I have frizzy hair and humid weather makes it worse. After this treatment, my hair stays manageable for weeks. This treatment fits easily into my monthly routine. Scalp felt comfortable, no itching. The 1600 ml bottle lasts long, so my mother and I share it. It is formaldehyde free, which was my main reason to buy.

As a man with short curly hair, I wanted something to reduce puffiness without looking unnatural. This treatment worked well. Applied it for the recommended time, and my hair now sits flat and neat. The smell is barely there. Quality feels professional.

Good product. Hair became straight and soft. No strong smell. Need two people for the back section. Value for money for 1600 ml.

Used this amino acid treatment after checking salon rates in my area. The full process took around 90 minutes, but the finish was very close to a professional straightening session. The big 1600 ml bottle gives good worth for the price, especially if two people use it. My hair did not feel burnt and there was no bad odour. I recommend it for rough, frizzy hair.

Bought this for my daughter's wedding preparation. We used it on two people and still have plenty left in the bottle. The 1600 ml quantity is huge compared to smaller kits. Hair stayed straight for almost three weeks with regular sulphate-free shampoo. It does not have that strong chemical odour, which is a big relief.

I was nervous about using a smoothing treatment at home because my hair is coloured and prone to dryness. This cysteine and amino acid formula was gentle enough. I followed the steps with a friend's help and the result was salon-like smoothness. The smell is almost nil, so no headache. My hair feels light, not greasy. I have used it once and got many compliments. Will update after a few months, but so far very satisfied.

I have coloured hair and was hesitant to use a smoothing kit. This one felt gentle because of the amino acid blend. The instructions were clear, and the gloves plus comb helped. My hair did not become poker straight, but the frizz vanished and it air-dries much smoother now. Packaging was neat, though the box was slightly dented in transit. Overall a reliable buy for Chennai humidity.

Bought this for my wife and later used it on my own hair. No formaldehyde smell, and application is manageable if you section the hair properly. Hair became straight and soft without looking flat. The 1600 ml pack is more than enough for two people. I will order it again once this bottle gets over.

The results are good and my hair feels straighter, but it took me more time than expected because I have long hair. The quantity is huge and packaging was sealed properly. It did not irritate my scalp, which is a big plus. I am giving four stars only because the instructions could be clearer for beginners. Still, for the price, it is a decent at-home option.

Good product. Hair became straight and manageable after first use. No bad smell. Delivery was quick.

Bought this mainly for my wife, but I tried it too on my rough hair. It made my hair softer and easier to manage. The cream is thick, so sectioning hair is important. No burning or itching. It does not smell bad like other treatments. I use a mild shampoo now and hair still looks neat. Good for men who want frizz control without a salon visit.

I was sceptical about doing a cysteine treatment at home, but this 1600 ml kit lasted for three sittings on my shoulder-length hair. The solution has no harsh chemical smell, which was a big relief in a small bathroom. I followed the instructions carefully and my hair felt salon smooth for almost two months. The upfront cost is higher than a shampoo, but it works out much cheaper than repeated salon visits. Already told my cousin to buy it.

I was worried about formaldehyde-free claims, but this treatment did not irritate my scalp. The smell is very mild, almost like a regular conditioner. I left it on as instructed and my frizz reduced a lot. Hair looks smooth in photos and my husband also noticed the shine. The 1600 ml bottle will last many months for my shoulder-length hair.

Ordered the 1600 ml kit after reading about cysteine treatments. Delivery reached my Bengaluru address in three days and the outer box was sealed properly. The cream and neutralizer bottles were full, no leakage. I have thick wavy hair, and one application with a friend's help made it noticeably straighter without that harsh burnt smell. Hair feels softer even after two washes. Takes time to section and apply, but worth it for the salon-like result at home.

I have thick wavy hair and was spending too much at the salon every few months. This 1600 ml kit is enough for multiple uses for me and my sister. The process takes time but the finish is very smooth. No harsh formaldehyde smell, which I really appreciated. My scalp felt comfortable during application. Hair stayed straight for almost three months with proper aftercare. Worth the price if you can follow instructions carefully.

The post-care products maintain shine and smoothness for long.

My hair felt silky and tangle-free after completing the full kit.

Easy to iron and style hair after this treatment.
