Lasio Keratin-Infused One Day Treatment 15.87 Fl. Oz

It damaged my color treated hair...changed the color (which professional treatments did also) but also broke off some pieces. It is not the same as a professional treatment but I do notice some improvement over having nothing in it.

I do my own Keratin Treatments for the past four years, I was convinced to purchase this product after reading the reviews and I must say it is the worst product I've ever used. I followed the instructions carefully and gave it four chances however I don't see ANY results!!Yes, it is easy to apply however once I washed it off my hair remains dry and frizzy. Waste of time and money.

I have had many many years of Keratin treatments. I was anxious to try this one. I found for my hair which is not curly just wavy that it did not straighten it at all. Maybe it does fight the humidity and frizz a bit but I wanted that straight look.I am disappointed and I have tried 4 times using the entire bottle up over the past year.Gotta try something else, maybe go back to the Rejunvenol 4 day which worked better than this.Try try again! sorry

So disappointed. The advertisement is misleading. It says formaldehyde-free, when the bottle clearly says CONTAINS FORMALDEHYDE.

Does not work at all...asking for refund...very irritating formaldehyde smell...had a headache entire 24 hrs and later...and so much suffering for nothing...my hair are as curly as they were...

I’ve been using Keritin since we were able to buy it on-line, first Coppola’s then another brand, this is my favorite. This keratin goes on so easily I can use less and it takes less time to hot iron. For the past year I started using it different than the label. I don’t have time to wash//dry first. Every time I wash and condition my hair, I take a teaspoon or so at a time into the palm of my hand. I put my head down, flip my hair over and start by rubbing into the underside. Then another teaspoon into the rest of my hair. Ends/Bangs/close to my scalp. My hair is barely shoulder length and thin so it doesn’t take much, sometimes I use a little more. I wait as long as possible, sometimes as little as 10 min, longer if I’m watching TV. Then I blow dry and hot iron as usual My hair looks fantastic every time I wash it. Which is only every 5-7 days. My hair is always soft, shiny, frizz free. The label wash/dry with no conditioner then sit for 30 min, dry again then hot iron - it wasn’t getting done because it took too long. I’ve not had any issues putting a little keratin on my shampood/conditioned hair. My hair is healthy after a year of doing this. Just a suggestion for a quick way to look goodThanks

Fake. Avoided me after I stated the product was not real. Don't spend your moneyI'm a professional hairstylist for 9 years and I have been using the lasio for 4. This one is not the real one. Different scent and consistency.. perhaps watered down or mixed with something else.

I very much appreciate being able to buy Lasio from this seller. This product is 5 star. There is nothing else on the market to compare. I can’t even imagine my hair without having this Keratin. I’ve tried every keratin product on the market for decades and this is by far the best. It can only be bought through a licensed seller which is a travesty but anyway I give my heartfelt thank you for selling this to me allowing my horrible frizzy breakaway hair to look silky and healthy. Thank you. Again. On another review I mentioned I don’t follow the manufacturer directions. I use this every time I shampoo. Shampoo/condition as usual (twice/week) Towel dry, then apply a few tablespoons of Keratin. Put the towel back on and wait 15 min sometimes longer. Blow dry and hot iron as usual. Don’t make a big deal of this, anyone can do it there is no messing up this product. For those who wait 2 months, no need to.
