Needs a Different Spray Bottle

I like the product itself, but the spray bottle it comes in is absolutely horrible. I'm not sure if I got a defective one, or it's just the way it is. It sprays in a single, straight stream which does not provide good, even coverage I was trying to spray into my hands or on my brush to apply, but I ended up just buying a different spray bottle altogether to transfer it to.

Packaging Needs Help

I love the actual product but the packaging is lacking. I would like a larger size option and I wish the spray nozzle had an actual spray setting instead of only a stream. It is hard to evenly distribute on my hair.

First of all, yes, the spray nozzle is terrible. I dont understand how that was passed. Anyway, the product itself is amazing! I sprayed it on damp hair and combed it through, let it sit for 10 minutes, then used No. 4 & 5 to wash and condition. I let it air dry and my hair felt so incredibly smooth. I styled it the next day when I noticed the shine on it. My hair is usually pretty dry, healthy, but dry. I can't stop looking at it and now I'll make sure to always include it in my hair routine.

Soft, beautiful hair starts with No.0

This makes a huge difference when used prior to No. 3. Saturate dry hair with No.0, wait 10 minutes. Saturate your already dampened hair with No. 3. Wait 10 minutes. Rinse both No.0 and No.3 completely. Shampoo with No. 4, condition with No. 5. Add No. 6 to roots for volume. Add No. 7. Seal that in with No. 9. Air dry or blow dry. Style or leave natural. Takes 10 years of aging off hair.

Great but sprayer is awful

Olaplex, love your products so much but what in the world are we doing with this sprayer? Literally any other mister would have worked but this is like a thin straight shot I have to apply in hands wasting product and then applying to hair. I think this works good but won’t purchase again unless a different sprayer is used.

Don’t bother if you aren’t getting the set

I really don’t understand why brands sell steps separately if the individual products don’t do any repair on their own? I bought this and really didn’t see the improvement, but perhaps it needs the next step paired with it.

Sprays funny- making a real mess, also it's not a life changer- no difference if u use it with no3, or just no3 by itself. Personally, I won't be buying it again.

After using this product, I dont feel it's necessary. I think using the number 3 treatment is enough. I didn't see a big difference in adding this into my routine.

After using this product, I have seen less plants in my hair, my hair is shiny and I have experienced more hair growth. I would definitely recommend this product for healthier hair.

A must have

I received the number 0 in a gift box and never used it , I always would just wet my hair then use the number 3 . I was skeptical at first but it made such a difference . The only con is if you have long hair you can easily use half a bottle and that’s using it conservatively. I would only use this twice monthly for that reason an application aplllla hbbnnnbottle for one application.

Sehr gut

Nummer eins für die Haare, sie sind sehr weich und ich hatte sehr kaputte Haare. Kann nur empfehlen

Significant difference

I really notice a significant difference when I use this before applying no 3 treatment to my hair. Easy to spray in my hair and doesn't hurt my wrists as I have carpal tunnel and have a harder time with sprays. 10/10 for me
