What’s inside the bottle?

The Multi-Peptide Serum for Hair Density is a concentrated formula that’s infused with peptide complexes, as well as Redensyl, a hair-growth galvanizer, and caffeine to stimulate blood flow in the scalp.

Suitable for straight, wavy, curly and coily hair types, the serum can also address common hair concerns like flakiness, dry scalp and volume loss.

Plus, the Multi-Peptide Serum is also vegan, cruelty-free and gluten-free.

How does it work?

Using the combination of plant-based extracts, peptides and Redensyl, the Ordinary serum is able to target stem cells in the scalp to improve their function and increase blood flow, allowing the hair to be well nourished.

Apparently, Redensyl is the first active ingredient based on regenerative medicine that can give you better results than a surgical hair transplant in just 84 days.

And in comparison, you’ll end up spending about $15,000 less on the Multi-Peptide Serum than you would a hair transplant, if you were considering.

Better yet, the formula makes up a lightweight, emollient base that can efficiently penetrate the scalp to provide a greater increase in hair density.

What are reviewers saying?

If you were dreading another serum that feels greasy or heavy on the scalp, then good news: according to Sephora customers, this blend is anything but.

Besides, with consistent use, new hair growth is guaranteed.

“This review is coming from someone who had insanely thin hair and has now been using this consistently for a year. And I can happily say it works!” a reviewer (pictured below) wrote on Sephora’s website. “You do have to use it consistently and don't start seeing results until a few weeks to a month, but patience is key and you will see a difference! Here are my before and after pictures over a year to see for yourself!”

Bonus: Some Sephora customers have shown that the Multi-Peptide Serum works on brows and lashes too — but, as with any product near your eyes, you should consult your optometrist before using to find out if it’s OK for you.
