this is probably going to be the olaplex product that is the most worth it. yeah its a too tiny bottle for a treatment that needs to be used consistently enough to see results, but you will see and feel results after 1 use. but consistency is definitely key, as with any product.i do keep it on for as long as possible, but under a shower cap, otherwise it dries and gets crunchy. it has to stay wet to work. some people here are saying to not leave it on for such a long time, so maybe i'll try that.of the olaplex products that are worth it:-no.3-no.6 leave in treatment. BUT i wish it had heat protection-the oil (idk the nunber) it has heat protection and will probably make your hair *feel* better temporarily for styling etc-no.8 hair mask. i got gifted this but ...

Hey everyone! I’ve been using this for years when I found out that other hair repairs had proteins (K18, Proof etc) that I’d used too often OR if your hair type is protein sensitive, protein of any type can dry out your hair and make it brittle, dull and excellerate breakage! I know weird right?! In other cases it strengthens hair. Unfortunately it dries out my hair (wavy fine hair, dry climate and hard water. The solution is Olaplex 3 one of the rare few repairs on the market that doesn’t do that and is great for curly and wavy hair :) if used as directed, you will see immediate results.

If there is only one product from Olaplex you need to try, it's No,3. After damaging my hair with harsh bleach and chemical services, it needed some TLC. No. 3 help to save my hair by reintroducing bonds and every time I use No. 3 my hair is silky soft afterwards. I do personally prefer to leave it on longer than the 10 mins to get max penetration, however, I've tried it for the 10 mins when I didn't have time to sit around for 30+mins, and it still left my hair super soft. If I could only buy one Olaplex product, it's No. 3 for me.

Saved my hair! I was worried about buying this product as I’ve seen very mixed reviews about the Olaplex brand in general. I have highlighted hair, and it gets very very dry especially at the ends. I bought this along with the shampoo and condionwr and it has changed my hair. It’s no longer dry and frizzy it’s very smooth and soft. I cannot recommend this enough to people are struggling with dry brittle hair. It’s amazing and my go to product!!
If there's one product I would NOT recommend it's this one. I saw this everywhere on Tiktok I had to try it. My hair was never really bad but I wanted to treat it to give it more shine. It literally made my hair turn like STRAW. The day after using it during my shower chunks were coming out. NEVER experienced this before I was scared. Now I'm stuck oiling it every day. After researching there's multiple lawsuits against them. Honestly I don't even know why it's still on the market it's absolutely horrible.
I have tried using this product a number of ways, using it after, rather than before shampooing, leaving it on overnight, leaving it on for an hour. I have noticed no discernable difference in my hair having used it weekly for six weeks. It is too late to return this astronomically expensive product. I was skeptical of the claims Olaplex was making, hair, after all, is dead, and science cannot make it magically repair itself, but was cajoled by my stylist into trying this, and I thought, maybe technology has advanced. Nope, no particular difference in my hair and no reduction of frizz or flyaways. I won't be repurchasing. A drugstore deep conditioning mask does a better job at a fraction of the price and it is not so cumbersome to use. Beware of cosmetic and hair ...

Alas, for me, this was no holy grail product. My hair is exactly the same and I am out $78.00 for the large size. Yikes.
Let's get one thing out of the way - this is a bond repair treatment to strengthen and repair the hair. It's NOT a deep conditioner/hydrating mask/smoothing oil/protein treatment etc. so don't expect the results as if you used one of the above! If you even decided to get olaplex no.3 I bet you aren't living in blissful ignorance thinking only shampoos exist and you normally use at least a conditioner and maybe oil/leave in/heat protector - so use them after this treatment, just as you usually do. This stuff is part of a system, which includes a conditioner, mask, leave-in, oil, and whatnot so get one of those if you need them, but no.3 is a treatment that doesn't replace the rest of your products.Whew. Now that I said it and you know what to expect, let's talk ... MoreLet's get one thing out of the way - this is a bond repair treatment to strengthen and repair the hair.

Now that I said it and you know what to expect, let's talk about my results. I have very fine, bleached hair that I had the audacity to bleach to platinum blonde, color with red box dye (twice) then bleach back to blonde. It's quite damaged, so I usually have to blow dry, otherwise the porosity will never let me air dry it. Here comes the magic - I used no.3 on wet hair after applying some no.0, put a shower cap on and sat down to work and forgot about it for a couple of hours, then washed it off, used my regular hydrating mask and conditioner and sat behind my desk again. In less than a couple of hours I remembered to finally blow dry my hair and realized that I didn't need it! It was perfectly dry and flowy, so all I needed was some leave in on the ends. This is a HUGE thing, indicating that olaplex really works - I know for a fact that the longer my hair takes to dry, the more damaged it is, so it went from >5hrs to less than two, plus a healthier feel as a bonus. It didn't make my hair shine like silicone oils do, but that's not something claimed it would so I'm fine with that. Will definitely keep using and will get more products from the system to go along with this treatment.
I have 3C hair that was severely heat damaged. I opted to do sew in extensions to allow regrowth, but as my hair is naturally dry, I went about 2 years without properly caring for it and my hair was dry, rough, and my curls had gotten to a kinky but severe lung tangled consistency.I tried EVERYTHING to just get my hair to fall back to its natural pattern and when I found this it was a game changer. My hair when straight is mid back in length so I was pretty sceptical about the size of this bottle at first. I got 6-7 treatments out of it. I used a little bit left it on for an hour or overnight with a shower cap on.My curls are soft, bouncy, they aren’t tangling as much and overall have life and shine. I’ve got the bigger bottle and now to a treatment every week ... MoreI have 3C hair that was severely heat damaged.

I’ve got the bigger bottle and now to a treatment every week when I wash and it’s worth it.I’m full time obsessed with this product and it’s allowed me to wear my hair natural for the first time in years without worry.
I only got a sample product so I only used this product the once but omg is my hair ever soft. My hair had been going through the ringer lately and was getting rather dry, got this as a free sample with my Sephora order I had ordered online and the results are definitely there. I wet my hair in the shower and got any leftover water from my hair, let this sit in my hair for 10 minutes, washed it out with my normal shampoo and conditioner and omg my was so so soft afterwords. If this product ever goes on sale I am for sure buying it cause it's so nice. Just make sure to leave this product on for 10 minutes on damp hair before going in with shampoo and conditioner or you might not get the results you're looking for but honestly this is a love for me.
So many bad reviews, I guess maybe it just works better for some people than others? I have bleach blonde fine curly/wavy hair. I ruined my curl pattern my entire teenage years and I early 20’s and dyed it every single natural colour(even went from black to blonde 2 times). Now that I’m in my mid twenties I’ve learned to love my curls and I thought I could never get them back. Well as you can see in the pics my hair is curly hair filled with volume now. THIS IS IMPORTANT I think some people need to realize is that this is a protein treatment it’s not for moisturizing so you need to use a SUPER hydrating conditioning mask do not use the number 5 regular conditioner it is not enough moisture. I use the olaplex 4-in 1 mask with the olaplex 0 , 3, 4 & 5 (YES I still use ... MoreSo many bad reviews, I guess maybe it just works better for some people than others?

I use the olaplex 4-in 1 mask with the olaplex 0 , 3, 4 & 5 (YES I still use the regular conditioner I will use two conditioners a regular one and a mask) I find number 5 not very hydrating so when I use the full olaplex system I use it as a detangle er then rinse my hair then put the mask on. And on any other normal day I use number 5 as a pre poo treatment. Now here is some pics as proof — the pics of me with my dark hair are without olaplex in my life, had no curl pattern, frizzy and puffy to gorgeous blonde defined curls
