Learn how to use The Ordinary Hair & Scalp Collection to support scalp health and hair density with a simple daily routine.
Quick answer
Use The Hair & Scalp Collection daily to exfoliate the scalp with glycolic acid and support hair density with a peptide serum, following a simple two-step routine.
Why scalp health matters for hair growth
A healthy scalp creates the best environment for hair to grow. Buildup of dead skin, oil, and product residue can clog follicles and slow growth. The Hair & Scalp Collection addresses this with two targeted products: a glycolic acid toner for exfoliation and a multi-peptide serum for density support.
What the collection includes and how it works
The set pairs a Glycolic Acid 7% Exfoliating Toner with a Multi-Peptide Serum for Hair Density. The toner gently exfoliates the scalp to remove buildup, while the serum delivers peptides that support thicker-looking hair. Both are designed for daily use and work together without irritation when applied correctly.
How to use the Hair & Scalp Collection for scalp health
- Step 1: Exfoliate the scalp with glycolic acid toner: After washing and drying your hair, apply the Glycolic Acid 7% Exfoliating Toner directly to your scalp using the nozzle or a cotton pad. Focus on sections where buildup is most visible. Leave on and do not rinse. Common mistake: applying too much toner can cause dripping. Use a small amount and part your hair to reach the scalp.
- Step 2: Apply the multi-peptide serum for density: Once the toner is fully absorbed (about 2-3 minutes), dispense a few drops of the Multi-Peptide Serum for Hair Density onto your fingertips. Massage gently into the scalp, focusing on areas where hair feels thinner. Do not rinse. Checkpoint: avoid rubbing vigorously. Gentle massage improves circulation without irritating the scalp.
- Step 3: Repeat daily and monitor progress: Use both products once daily, preferably in the evening. Consistency is key — visible improvements in scalp texture and hair density typically appear after 4-8 weeks of regular use. Common mistake: skipping days or alternating products inconsistently reduces results. Stick to the daily routine.
