Olaplex No 4 & 5

5 stars out of a maximum of 5

I have long fine(ish) hair and I wanted something to get it stronger and thicker. After at least 10 washes there's an amazing difference in the strength and thickness of my hair and less hair loss. Best hair combo I've tried EVER so far it's pricey but a great investment for long term hair care and don't even need a lot because it gets so soapy and my hair goes past my waist.

Weight without grease

5 stars out of a maximum of 5

My hair is mature and quite fine. This shampoo gives weight to my hair so I don’t have the overnight frizzes, but it doesn’t leave my hair greasy.

Gentle Shampoo

3 stars out of a maximum of 5

This is a good and gentle shampoo for chemically treated or colored hair, but what i found annoying is that it leaves my scalp itchy. i have used many other shampoos but never had this issue. so now i used this shampoo for whenever i want to double shampoo. i use this for first wash and then use a different shampoo which doesn't leave my scalp itchy.

Saved my hair

5 stars out of a maximum of 5

I genuinely cannot recommend the Olaplex range enough. I talk about it to anyone who will listen. This, alongside the rest of the range, has saved my bleached hair. Gone are the frazzled ends -- lush, silky strands now exist in their place. Like other reviews state you really don't need a lot at all. An amount the size of a two-pound coin does my whole head of relatively thick, chest-length hair very easily.

Amazing!

5 stars out of a maximum of 5

I’ve always heard a lot of good things about Olaplex in the past and finally decided to buy the shampoo and conditioner together, and I can honestly say it’s so amazing! I don’t think I’ll ever change now, it’s worth every penny! My hair has been a lot less frizzy, shiny, and smoother and I’ve also notice slight hair growth within a month of using it. Worth a try! I usually wear hair extensions (I don’t know what the product will be like with them in) but I honestly think my hair has improved so much that I no longer need them!

IT SAVED MY HAIR!!!!!!

5 stars out of a maximum of 5

So I had a very rough 2019 to say the least and the result of that was that I had a huge amount of hair loss. I’m talking going from thick locks to no thickness at the back (I basically had a mullet). I tried loads of other products such as Ogx thickening shampoo and conditioner but nothing worked. My auntie bought me the shampoo and conditioner from Olaplex and I was sceptical, to say the least, but my goodness I was wrong. This stuff works miracles in the space of three months my hair has come on leaps and bounds. It’s healthier, shinier and most importantly, thicker. Absolute 10/10 holy grail product. If you’re not sure try it, it’s insane!

As Good as promised.

4 stars out of a maximum of 5

Very Good product leaves my hair soft and hydrated. It lathers up well, only need a small amount. It's a bit pricey but well worth it. I use it 2-3 times a week, as I have oily roots (and dry ends).

Need to use full for best results

5 stars out of a maximum of 5

After bleaching my hair it became hard to brush and manage and felt like straw. I have been using the olaplex shampoo No4, conditioner No5 and No3 hair protector and am amazed by the results. My hair is now soft, shiny and can easy get a comb through it, healthiest my hair has been for a while. Would highly recommend, but would use all 3 products to get the best results.

Not just for coloured hair.

5 stars out of a maximum of 5

Even though I do not colour my hair, I am always looking for hair products that will help tame my thick frizzy mane. The first thing that I love about this shampoo is how little you need to get a nice lather, I am a chronic overuser of hair products and squeezed a big glob onto my hand the first time and it was way too much! I used this in conjunction with the Olaplex No 5 Bond Maintenance Conditioner and my hair felt so clean and soft afterwards. I am not the biggest fan of the smell as I find it a bit too sweet but I find that it doesn't linger, and for the results its worth it.
