Squeeze a few drops (about 1/4 to 1/3 of the pipette) directly onto your scalp, focusing on areas of thinning or concern.
Massage Thoroughly
Use your fingertips to massage the serum into your scalp for 1-2 minutes. This stimulates blood flow and aids absorption.
Leave In Overnight
Do not rinse. Leave the serum on your scalp overnight for maximum absorption. You may wash your hair the next morning if desired.
Be Consistent
Apply once daily, ideally at bedtime. Results typically appear after 8-12 weeks of consistent use. Continue for 4-6 months for best results.

❓ Frequently Asked Questions
DECIEM has not specifically tested this product on pregnant or breastfeeding individuals, so they cannot confirm its safety during these times. The formula contains Gluconolactone (a PHA), which some dermatologists recommend avoiding during pregnancy as a precaution. Additionally, some ingredients like caffeine are absorbed through the scalp. We strongly recommend consulting your healthcare provider before using this product during pregnancy or breastfeeding.
No, this serum is NOT fungal acne safe. It contains Polysorbate 20 and PEG-40 Hydrogenated Castor Oil, which are known to feed the Malassezia yeast that causes fungal acne and seborrheic dermatitis. If you have these conditions, this product may trigger itching, flaking, and breakouts on your scalp. Consider looking for a fungal-acne-safe alternative or consult a dermatologist for recommendations.
Since this is a scalp treatment rather than a facial product, it won't interact with your facial skincare routine. You can use your regular retinol, vitamin C, or AHA/BHA products on your face while using this serum on your scalp. The formula already contains Lactic Acid and Gluconolactone (mild exfoliants), so it works synergistically to improve scalp health. No conflicts with your facial routine.
This serum is suitable for ALL hair types including straight, wavy, curly, coily, fine, thick, and afro-textured hair. It's particularly beneficial for those experiencing hair thinning, reduced density, or traction alopecia. The lightweight, water-based formula won't weigh down fine hair or disrupt curl patterns. It's also color-safe and works well on chemically treated or keratin-treated hair.
Most users begin noticing reduced shedding within 4-6 weeks of consistent daily use. Visible new growth and increased density typically become apparent at 8-12 weeks. Maximum results are usually achieved after 4-6 months of continuous use. Individual results vary based on the cause and severity of hair thinning. Consistency is key – skipping applications will delay results. The product needs to be used indefinitely to maintain benefits.
Apply to a clean, dry scalp after washing and towel-drying your hair. Use ideally at bedtime as the final step in your hair routine. Do not rinse out – it's a leave-in treatment. You can wash your hair the following morning if desired. If you prefer to use it in the morning, be aware that some users find their hair looks less fresh. Avoid applying styling products directly over the serum.
This serum has a low comedogenic rating of 1/5, meaning it's very unlikely to clog pores or hair follicles. The water-based, lightweight formula is designed to absorb quickly without leaving residue. However, if you experience scalp acne or clogged follicles, discontinue use and consult a dermatologist. The formula contains no heavy oils or silicones that typically cause buildup.
The product has a PAO (Period After Opening) of 12 months. Store it in a cool, dry place away from direct sunlight. No refrigeration is required. One 60ml bottle typically lasts 1-2 months with daily use, depending on how much product you use per application and the size of the area you're treating. The dropper dispenser helps control the amount used and maintains product hygiene.
Verdict: The Ordinary Multi-Peptide Serum for Hair Density delivers impressive value with its 21.15% concentration of five patented peptide technologies at a fraction of competitor prices. Backed by science-based ingredients like REDENSYL™ and caffeine that show real promise in clinical studies, this affordable serum is a solid choice for those experiencing early hair thinning who want to try a non-prescription approach. While results require patience (8-12+ weeks) and not everyone responds equally, the overwhelmingly positive reviews and excellent price-to-performance ratio make this a worthwhile addition to any hair wellness routine. Not suitable for fungal acne-prone scalps or those needing pregnancy-safe formulas. For advanced hair loss, prescription treatments may be more effective.

❓ Frequently Asked Questions
DECIEM has not specifically tested this product on pregnant or breastfeeding individuals, so they cannot confirm its safety during these times. The formula contains Gluconolactone (a PHA), which some dermatologists recommend avoiding during pregnancy as a precaution. Additionally, some ingredients like caffeine are absorbed through the scalp. We strongly recommend consulting your healthcare provider before using this product during pregnancy or breastfeeding.
No, this serum is NOT fungal acne safe. It contains Polysorbate 20 and PEG-40 Hydrogenated Castor Oil, which are known to feed the Malassezia yeast that causes fungal acne and seborrheic dermatitis. If you have these conditions, this product may trigger itching, flaking, and breakouts on your scalp. Consider looking for a fungal-acne-safe alternative or consult a dermatologist for recommendations.
Since this is a scalp treatment rather than a facial product, it won't interact with your facial skincare routine. You can use your regular retinol, vitamin C, or AHA/BHA products on your face while using this serum on your scalp. The formula already contains Lactic Acid and Gluconolactone (mild exfoliants), so it works synergistically to improve scalp health. No conflicts with your facial routine.
This serum is suitable for ALL hair types including straight, wavy, curly, coily, fine, thick, and afro-textured hair. It's particularly beneficial for those experiencing hair thinning, reduced density, or traction alopecia. The lightweight, water-based formula won't weigh down fine hair or disrupt curl patterns. It's also color-safe and works well on chemically treated or keratin-treated hair.
Most users begin noticing reduced shedding within 4-6 weeks of consistent daily use. Visible new growth and increased density typically become apparent at 8-12 weeks. Maximum results are usually achieved after 4-6 months of continuous use. Individual results vary based on the cause and severity of hair thinning. Consistency is key – skipping applications will delay results. The product needs to be used indefinitely to maintain benefits.
Apply to a clean, dry scalp after washing and towel-drying your hair. Use ideally at bedtime as the final step in your hair routine. Do not rinse out – it's a leave-in treatment. You can wash your hair the following morning if desired. If you prefer to use it in the morning, be aware that some users find their hair looks less fresh. Avoid applying styling products directly over the serum.
This serum has a low comedogenic rating of 1/5, meaning it's very unlikely to clog pores or hair follicles. The water-based, lightweight formula is designed to absorb quickly without leaving residue. However, if you experience scalp acne or clogged follicles, discontinue use and consult a dermatologist. The formula contains no heavy oils or silicones that typically cause buildup.
The product has a PAO (Period After Opening) of 12 months. Store it in a cool, dry place away from direct sunlight. No refrigeration is required. One 60ml bottle typically lasts 1-2 months with daily use, depending on how much product you use per application and the size of the area you're treating. The dropper dispenser helps control the amount used and maintains product hygiene.
Verdict: The Ordinary Multi-Peptide Serum for Hair Density delivers impressive value with its 21.15% concentration of five patented peptide technologies at a fraction of competitor prices. Backed by science-based ingredients like REDENSYL™ and caffeine that show real promise in clinical studies, this affordable serum is a solid choice for those experiencing early hair thinning who want to try a non-prescription approach. While results require patience (8-12+ weeks) and not everyone responds equally, the overwhelmingly positive reviews and excellent price-to-performance ratio make this a worthwhile addition to any hair wellness routine. Not suitable for fungal acne-prone scalps or those needing pregnancy-safe formulas. For advanced hair loss, prescription treatments may be more effective.
