Nellen Blonde Keratin Hair Straightening Kit · Same Day Wash · No Formaldehyde

Does what it says! Hair left smooth and soft for 8 weeks. Already ordered again. Only criticism is that it would be good if the kit was supplied with gloves and applicator brush. Other than that excellent product!

Not sure what everyone else is raving about, I had a horrible experience with this product. First of all, the shampoo is only 30ml ..I have long hair so not sure how I could manage to wash my hair the recommended four times. The next product the spray pump didn't work, so that was annoying. Plus this was also a small amount and wasn't enough to cover my hair. The third product you are meant to comb through your hair, then wait 30 minutes then blow dry and straighten. I'm not sure if this was some kind of joke, but imagine putting glue on your hair and then trying to comb it through. I just about managed, and after thirty minutes my hair was such a goopy mess there was no way I could even get a comb through it, let alone try to blow dry it or take sections to flat iron! So basically after losing chunks of hair in a grand effort for this to work I gave up, and had to wash all that garbage and all my hard spent money down the drain. I'd like to find the inventor of this product and kick them in the shins.

I tried saloon keratin treatment 3 times and Brazilian hair straightening home kit couple of times in past. I have highlighted hair colour since 2012 so I couldn't use any keratin treatment since then.Having a baby and feeling no time to deal with my long and frizzy hair started to think semi permanent straightening again. I was looking for a budget option. When I searched for blonde hair I found this product.So, here's my opinion:If you never use home kit before, I need to warn you; depend on hair length, you need to spend min 4 hours! I have long hair it took me to complete 5 1/2 hours...Instruction is very easy. Nothing complicated at all.At the end it's chemical treatment but there is no nasty smell during any stage of application comparing other kits.Unfortunately the first bottle solution supposed to be atomiser bottle spray wasn't working so I had to pour in a cup and applied with tint brush. Result: it wasn't enough for my full hair.... I kept this product almost 3months on side because of my busy "baby" schedule, after 3 months I was so desperate to use it. So I didn't want to contact seller, ask replacement and wait for it. But before you use the kit, it's good idea to check this.There is no hair clips, brush, cover, gloves etc. unlike the other brands...I was pretty upset when atomiser bottle not working, couldn't get any hair on my top which was frizzier but I decided to take risk and complete the each step.After long time consuming application result wasn't bad. I can't say my hair is so sleek but it didn't look frizzy anyway. I am assuming if I could have "working" atomiser bottle and sprayed it evenly I would be very happy at the end.Yes I feel my hair dry, even I use coconut hair milk but I had same result after my saloon treatments as well so I was expecting this.I will add my picture in 6- 8 weeks as it say it can stay straight up to 12 weeks, so we all can see 6-8 weeks update.

this is the best thing I've ever used made such a difference I can finally go out and my hair stays the same I'm on my fourth kit

DO NOT BUY THIS PRODUCT. This product has left my hair dry damaged and with the texture of straw, It is weak, difficult to brush as it angles and has snapped off at the front . It did not straighten hair, and left it frizzy rather than glossy as keratin straightening should do. I also question wether it really is made in London as advertised, when looking at the spelling mistakes in the instruction. I would leave no stars if possible as I regret ruining my hair by using.

Very good product, excellent result, i am very satisfied and Will surely bay it again

Fantastic product. Had it done by my hairdresser in November and I have had frizz free hair since. Well definitely be buying agan

Does what it says if you follow the instructions very carefully :)
