No.0 Intensive Bond Building Hair Treatment™ - Haarbehandlung

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

So far I've been using this in the repair bundle. My main issue is the bottle shoots a single stream vs a spritz. In addition, the amount of product I have to use on my thick hair for this is insane. I used this 3 times and the bottle is almost gone. I wish it came in a bigger size.

Good stuff but the spray nozzle breaks every time!

Lost a star because the spray nozzle breaks every time and drives me absolutely insane lol

Totally worth it!

I use this along with Olaplex step 3 twice a week, on wash days, NO EXCEPTIONS! This has saved my hair from breaking after bleaching.
