N°4 Bond Maintenance™ - Shampoo

Great

This made my hair so smooth I absolutely loved it.

Moisturizing for dry damaged hair

This is hands down the best shampoo I’ve ever used. It’s very hydrating and leaves hair manageable and soft. I can’t say enough of it. Leaves no residue cleans without stripping hairs natural oils.

While I absolutely love other products in the Olaplex range such as n.3 and n.9, this product unfortunately did not work for my damaged type 4/permed hair. It left my hair feeling drier than usual and like straw no matter how much or how little I used it in my routine.

I definitely recommend buying this product for dry, damaged hair!

A new must have

I used this for over 4 months and have never seen my hair as healthy and shinny as this! Highly recommend for anyone struggling to restore their hairs health or who wants to improve the general appearance of their hair!

A must-have for damaged, brittle hair!

My hair was falling out and so brittle before using this product. Within weeks of incorporating this product into my hair care routine, I have noticed less breakage, more volume and overall healthier hair. My hair and scalp feel clean but not stripped after shampooing with this product.

Not for all hair types!

This product started to break and damage my hair. I did a lot of research after noticing Mt hair coming out in chucks.. it turns out this product is not for every hair type that's why so many people have amazing results and others not so lucky. I will explain my hair so maybe anyone who has similar hair should be cautious: I have a lot of hair but it is very fine, it gets greasy quick and splits easily. Olaplex really needs to look into which hair types shouldn't use this product.

It is ok ok but not that good

After using this, my scalp gets oily after two days and it doesn’t help with white flakes on the scalp. However it gives a smooth hair for two days.

NOT for blond highlighted hair - major damage

I used the shampoo, conditioner and #3 for the past 7 months on an occasional basis as per instructions and the products have completely dried out and damaged my hair. They also caused a massive keratin build up and had to go to the hair dresser to fix my hair. Do not use this product if you have fine, blond highlight hair. It will ruin your hair.

Breakage and hair loss after using for <1 month

Unfortunately after using this product for a few weeks my hair suddenly started breaking and falling out. I have always had extremely strong and thick hair, and now I have extremely weak and brittle hair since I started using this product.

If I could, I would leave a negative star review.

After 8 months of using Olexplex shampoo & conditioner, my hair became extremely fine & brittle and began to fall out in clumps. I genuinely thought I had a problem with my hormones until I switched to a different brand.

Great shampoo

Great product, have been using it for years. Color safe and hydrating
