What are the key ingredients used in The Ordinary Multi-Peptide Serum for Hair Density?

The key ingredients are the extracts or technologies used in The Ordinary Multi-Peptide Serum for Hair Density. These trademarked ingredients that make it a source of healthy hair treatment are as follows:

Redensyl: It activates the stem cells and targets human fibroblasts from the dermal papilla for improving hair density. It contains Camellia Sinensis Leaf Extract and Larix Europaea Wood Extract.

Procapil: It increases blood flow in the scalp. This results in a thicker hair appearance by nourishing the hair. It is a peptide complex that increases blood flow to promote hair growth. It mainly consists of Trifolium Pratense Flower Extract and Acetyl Tetrapeptide-3.

Baicapil – It works to increase the hair density and contains Triticum Vulgare Germ Extract, Scutellaria Baicalensis Root Extract, Glycine Soja Germ Extract.

Lactic Acid – It is an Alpha Hydroxy Acid (AHA) that promotes microcirculation, helps in getting rid of excess sebum (responsible for oily or greasy texture), and exfoliates the scalp.

AnaGain – Based on Pisum Sativum Extract (Organic pea sprouts), it stimulates specific signal molecules in the dermal papilla that are responsible for reactivating hair growth.

Directions to use

The instructions on how to use the serum in “The Ordinary” hair serum is based on what works for me.

Nevertheless, here’s a quick lowdown on the steps:

  1. It is ideal for use before bedtime and can be applied once daily.
  2. Apply a few drops in the scalp or more as needed.
  3. Next, massage it thoroughly into the scalp
  4. Do not wash your hair after application as it is a leave on treatment for hair.

It is important to note what is the right time and when the serum is too much or too low to work its charm. In the ordinary hair serum review, I would like to share my personal tips on its application.

Using a dropper helps you add the drops in the proper amount over the target areas. Then, gently massage the oil for 5 to 10 minutes to promote blood circulation.

As for the right time, the brand suggests applying it at night and leaving it on. This is true, but don’t go overboard as a daily routine. The fact is, right application is more effective than overuse. Therefore, l use it every third day before bed and it blends well with the hair wash schedule. You can do something similar based on your schedule.


  • Better lustre
  • Improved blood circulation
  • Proper greasing
  • Thicker, volumized hair
  • Prevents dandruff and dry scalp conditions

Consistency is the key. Therefore, it goes without saying that you cannot expect it to work after a few applications every now and then. I started noticing the difference after using the whole bottle. The hair looked less sparse, soft with a silky, shiny texture.

The formula is affordable. After a few months of regular use, thickness and density are two things anyone can expect. You can find it in any “The Ordinary” hair serum review.


  • Ideal for people with dry or flaky scalp as it is great for greasing the hair.
  • It prevents hair damage and nourishing it by facilitating blood flow.
  • It provides luscious, thicker, denser hair.
  • A great and affordable alternative that lasts longer.
  • It is a cruelty-free, vegan product.
  • It is free from several chemicals and is gluten-free, alcohol-free, but free, and silicone-free.


It is a leave-on serum, so you might want to avoid using it during the day immediately before important events.

My take on The Ordinary Multi-Peptide Serum for Hair Density

It is a great Volumizing hair serum that is suitable for all skin types and textures. It results in healthier, thicker, and denser-looking hair. The emollient base is effective in penetration. The regular use shows results if used properly. Anyone can use it for treating dry scalp and get thicker locks.

The best thing about this hair product is it is affordable and cruelty-free. As it is gluten-free and nut-free, many people suffering from allergies will find it a better alternative. It is affordable in comparison to overpriced hair treatments or transplants. You can also add supplements for a healthy hair care regime as directed by your doctor.

Based on thousands of feedbacks, we can say that “The Ordinary” hair serum has gradually reduced baldness over time with regular use. My take on the formula is it definitely reduces the appearance of fine hair and improves hair density in less hair areas.
