N.º 4 Bond Maintenance® - Champú

Great for damaged hair

Love this shampoo, used for a few years now. Really helped with hydration as I bleach my hair

Bad experience

if you have wavy or curly hair, don't use this shampoo because it straightens your hair. It's the first time I've used olaplex to hydrate my curls But it has straightened my curls 😢 And the aroma gives me nausea and headache 🤕

Good brand

Good brand and trustworthy products I enjoy using for smooth and silky hair.

Nice shampoo

Leaves my hair softer. Pleasant smell; not overbearing. Once hair is dry, feels like their is a coating on my hair and feels a little stiff, but after combing it feels fine.

Obsessed

This stuff is unreal. My hair is so silky smooth. I use it with no5, no6 & no7. Even washing and styling my hair daily it feels like silk. Obsessed.

Love this shampoo

I have been using Olaplex No 4 for a couple of years now. I don't wash my hair every day, only twice a week. Whenever I use Olaplex, my hair feels very soft. I just love it. About every month, I use the Olaplex for grey hair and I always get compliments on my hair.

Amazing!

Amazing shampoo, has made such a difference to the texture & length of my hair. Would highly recommend!

Shine Softness

The shine after use was great, my hair felt very soft

Caution causes extreme breakage

I don't understand how this product is still on the market. This shampoo and conditioner is anything but nourishing or hydrating. Instead my hair has broken all over, completely thinned out and is ruined. Used to be able to blow-dry with round brush and after using this shampoo for 6 months, my hair is frizzy, split, dry and a mess after drying. The appeal for me while using this shampoo and conditioner approx 2-3 times per week is the great lather. Small amount lathers up great; but I've never used a hair product in 56 yrs that was so damaging to my hair. Assuming it will take two years to completely grow out and return to my normal. Currently using a true nourishing brand and told to avoid any products or protein treatments that will exacerbate the problem. But you can't "repair" broken hair shafts; time will be the only remedy.

Smells exactly like dish soap.

I received a set of 4 products as a holiday gift from a family member and gave it a try since it seemed very nice, but my hair actually feels worse than it did before (SUPER dry, no shine, gets tangled/matted faster than ever) on a cheaper brand. However for me, it’s the SMELL!! This shampoo smells exactly like dawn dish soap and VERY strongly of it too- when I’m lathering it on my head, it’s just like I’m scrubbing pots in the sink! Unmistakably so! Horrible scent for a hair care product, I have no idea where people are getting the “smells nice!” comments because the smell is…not at all grapefruit or citrus. Incredibly disappointed.

Not Impressed

I have fine color treated hair that I wash every 3-4 days. I found this shampoo and conditioner left my hair heavy, limp and not feeling clean. My hair was also extremely tangled when drying, the bonding leave in didn’t help and the oil was a disaster. The packaging is the worst! The bottle is hard to squeeze, doesn’t stand upside down in the shower and left a lot of waste in the bottom of the bottle. I had to buy airless pumps and transfer it into the new bottle. Not worth the ridiculous cost.

Healthier hair

I have switched to Olaplex shampoo a while ago and I don't look back. My hair is visibly stronger and healthier. The only downside is the price.
