How Does The Ordinary Multi-Peptide Serum Work?
The serum works from different angles and different stages to achieve a common goal, which is helping the serum achieve fuller, healthier, and denser-looking hair.
Now, we wanted to know more and into details, how this multi-peptide serum works to help in growing dense and healthy-looking hair. Here’s what we found out:
First, the serum contains peptides that help increase blood circulation in the scalp. Good blood circulation in the scalp helps deliver essential nutrients and oxygen for hair growth. In addition, the manufacturer says that the coffee in the serum makes it easier for the serum to be absorbed into the scalp.
According to a study published in the International Journal of Molecular Studies by Su Bin Hwang, peptides may also mimic the effects of growth factors. This signals the hair follicles to enter into the growth phase to help hair grow thicker and fuller[1].
Castor oil is also another ingredient the manufacturer claims to use in this serum. It has been used for years to help in hair growth and overall health of the hair. According to a study published by Venkataram Mysore in the International Journal of Trichology castor oil is a good moisturizer and sets a good environment for hair growth and overall hair health[2].
The Ordinary Multi-Peptide Serum Ingredients – Are They Safe?
Here are some of the key ingredients said to be included in the serum:
Pisum Sativum Extract
Pisum Sativum, more commonly known as the garden pea, might hold a surprising benefit for your hair. This beneficial ingredient is also featured in Biotin Hair Growth Serum, where Pisum Sativum serves as a key component. Pea sprouts, the young shoots of the pea plant, have been increasingly used in hair care products to promote hair growth.
Pea sprouts are packed with essential vitamins, minerals, and antioxidants. These include Vitamin C, zinc, and iron, all of which are crucial for hair health. They also contain protein, a key building block for hair follicles.
Studies have shown that Pea Sprout Extract can positively influence hair growth. A study published in the National Institutes of Health by Torsten Grothe et al., revealed that it may shorten the resting phase of the hair growth cycle and strengthen hair follicle stem cells. This can potentially lead to increased hair density and growth[3].
Glycine Soja Germ Extract
Glycine Soja Germ extract, also known as soybean germ extract, is a substance derived from the germ of soybean seeds. This extract is rich in various nutrients and bioactive compounds. These components have shown potential benefits for hair health.
A study published in Nutrients Journal by Elsa C. Dinsdale suggests that the isoflavones in soybean germ extract may mimic the effects of estrogen in the body. Estrogen plays a role in hair growth regulation. By mimicking estrogen, these isoflavones might stimulate hair follicle activity and promote hair growth[4].
Larix Europaea Wood Extract
Larix Europaea Wood Extract, also known as European larch extract, is a natural ingredient derived from the wood of the Larix Europaea tree. It’s gaining traction in the hair care world for its potential benefits in promoting hair growth and overall hair health.
A study published in the Pharmaceutics Journal by Seyeon Park suggests that this ingredient might play a role in stimulating hair follicles. This stimulation could potentially encourage hair growth and reduce hair loss. One key component is its presence in a popular hair loss complex called Redensyl[5].
Caffeine Extract
Caffeine extract is a concentrated form of caffeine, the stimulant found naturally in coffee, tea, and cocoa beans. It can be obtained through various methods, including solvent extraction or water processing.
A 2007 study published in the International Journal of Trichology investigated the effects of topical caffeine on hair growth. The study showed that applying a solution containing caffeine seemed to stimulate hair growth compared to a placebo[6].
How to Use?
- Dosage: Apply a few drops of the serum directly to the scalp, focusing on areas with thinning hair.
- Frequency: Use once daily, preferably in the evening, to allow the serum to absorb overnight.
- Application: Massage the serum gently into the scalp with your fingertips for better absorption.
- Consistency: For optimal results, use the serum consistently for at least 2-3 months.
- Avoid: Do not apply on broken or irritated skin. Avoid contact with eyes, and wash hands after application.
- Tip: Combine with a gentle scalp massage to improve blood circulation and enhance serum absorption.
Benefits of The Ordinary Multi-Peptide Serum
Here are some key benefits of using this serum on your hair:

- Supports healthy scalp – The serum is applied directly to the scalp. The manufacturer therefore claims that it works directly through the scalp to help users achieve healthier-looking hair. This may also means that using it may leave you with a healthy scalp.

I’ve been using The Ordinary Multi-Peptide Hair Serum for three months and started seeing baby hairs along my hairline within five weeks. My fine hair now looks fuller, has more volume at the crown, and styles better. The watery texture absorbs quickly, leaves no greasy residue, and has no strong scent. The dropper also makes it easy to apply directly to thinning spots without any mess.

If you have skin allergies or sensitive skin, be cautious. Everywhere I applied the serum turned into a rash. I have latex and nickel allergies, so maybe it contains something that triggered my reaction. I’d steer clear if you’re allergy-prone. ~ Elle, Verified Purchase

I purchased this product over a month ago and finally received it, but when I opened the package, there was glass everywhere. It had arrived broken, which was very frustrating. ~ Jasmin L., Verified Purchase
I have been using this serum for 2 months and haven’t seen any results so far. I’m going to continue for the next few months and hope it starts working.
