Whether you go to a salon to dye your hair or go the DIY route at home, chances are you know what it’s like to deal with damaged strands.

But there’s one treatment Amazon shoppers swear by to repair dry, damaged hair and maintain its health. With more than 2,700 reviewers and a 4-star average rating, Olaplex Hair Perfector No. 3 Repairing Treatment is consistently a best-seller in the hair category,

“This is quite possibly the most amazing treatment/conditioning mask that I've ever purchased for my hair. I have bought a lot of hair products and nothing compares to this Olaplex,” raved one happy customer. “I was concerned at first that I would go through the bottle really quickly. However, you don't seem to need that much each time due to the consistency of the product. I use it about once per week. I notice a huge change after I use it. My hair is much more sleek and soft without being heavy or oily.”

Olaplex No. 3 doesn’t just condition dry hair, it repairs and strengthens hair through bond-building technology. ”This product literally saved my hair from total breakage. It strengthens like no other — not even protein treatments are this good,” added another reviewer, who called it a “miracle product.”

And the treatment doesn’t just get the seal of approval from Amazon shoppers — the professionals are also fans.

Hairstylist and founder of her namesake salon, Sally Hershberger tells Yahoo Lifestyle that colorists at the salon mix it with the color to minimize damage, but it’s a great at-home treatment, too.”The treatment is used to make sure that hair stays protected during the color process. After the treatment, it is used to keep hair healthy and damage-free between appointments,” Hershberger explains.

When you use it at home to nourish dry strands, just apply it from root to tip on damp, towel-dried hair and leave it on for 10 minutes before applying your regular shampoo and conditioner.

“Olaplex is best for anyone who has their hair colored with bleach,” adds Hershberger. “It is most beneficial for platinum blondes, but even if you just have a few highlights, you still want to use the Olaplex because any amount of bleach can damage hair and this treatment keeps hair well-protected.”

A 5-star reviewer pointed out that it helped revive their “thin, flat, unhealthy” hair. “Due to an illness, I was struggling with just bad hair,” she wrote. “Dry, dead, nasty hair. My hair was falling out too. This brought it back to life. I use it once a week and it really helps keep the ends of my hair nice and clean and soft. It also makes the new hair growing in strong and soft as well. I highly recommend this, it is worth the price.”

At $28, it’s a spurge, but it’s so easy to use and yields results that make it well worth its price tag, as most reviewers point out.

“I would say that if your hair is severely damaged, the price is worth it, and the product does exactly what it claims to do,” noted another reviewer. “It really is a miracle, worth every penny!”
