How to Use OS-01 HAIR Serum for Scalp and Hair Care

Quick answer

Apply OS-01 HAIR Peptide Scalp Serum to a clean, dry scalp once daily, focusing on areas of thinning. If you use the OS-01 HAIR Dermaroller, roll gently before applying the serum to boost absorption. Fill the OS-01 HAIR Glass Bottle from your refill and use the dropper for precise, hygienic application.

Why a consistent scalp routine matters

OS-01 HAIR is a scalp serum powered by OS-01, which is proven to target cellular senescence, a key contributor to hair loss and thinning. Because hair growth cycles are slow, the serum works best when you apply it consistently rather than in bursts. A simple daily routine removes guesswork and helps you stay on track.

What you need before you start

Gather your OS-01 HAIR Peptide Scalp Serum refill, the OS-01 HAIR Glass Bottle with dropper, and optionally the OS-01 HAIR Dermaroller. The glass bottle is empty and designed for use with the serum, so you can refill it and apply with precision. The dermaroller has 0.25mm medical-grade stainless steel needles and 540 microneedles to create gentle micro-channels.

Step-by-step application

Follow this order each time you apply the serum. Adjust the frequency only if your scalp feels irritated.

• Step 1: Start with a clean, dry scalp. Wash your hair and scalp with a gentle shampoo, then dry thoroughly. Applying serum to a damp or dirty scalp can dilute it or trap residue.
• Step 2: Fill the OS-01 HAIR Glass Bottle. Twist open your OS-01 HAIR refill and carefully pour the serum into the glass bottle. Attach the dropper. Do not overfill; leave a little space for the dropper to displace liquid.
• Step 3: Part your hair to expose the scalp. Use your fingers or a comb to create clean part lines, section by section. Focus on areas where you notice thinning or want more density.
• Step 4: Apply the serum directly to the scalp. Use the dropper to place small drops along each part line, about 1–2 cm apart. Do not apply to the hair strands; the serum needs to reach the scalp.
• Step 5: Massage gently. Use your fingertips to spread the serum evenly across the scalp. Avoid vigorous rubbing, which can tangle hair or irritate the scalp.
• Step 6: If using the OS-01 HAIR Dermaroller, roll before serum. Roll gently over the scalp in horizontal, vertical, and diagonal directions, then apply the serum. The dermaroller creates micro-channels that boost absorption of OS-01 HAIR. Do not press hard; a light, even pass is enough.
• Step 7: Let it absorb. Leave the serum on the scalp. Do not rinse immediately. Style your hair as usual after it dries.

Common mistakes to avoid

Applying too much serum can make hair look greasy and waste product. One dropperful per section is usually enough. Skipping days undermines the benefit; set a daily reminder. Using the dermaroller on irritated or broken skin can cause discomfort, so skip it if your scalp is inflamed. Also, do not share your dermaroller, and replace it according to the manufacturer’s guidance.

How to fit OS-01 HAIR into your day

Most people apply OS-01 HAIR at night before bed, since it does not require rinsing and can work overnight. If you prefer mornings, apply after styling to avoid disturbing the serum. Pair it with your existing hair care products, but avoid layering strong actives directly on top. The 3 Month Supply Refills make it easy to stay stocked without buying a new bottle each time.

Your daily OS-01 HAIR routine

1. Cleanse and dry: Wash your scalp and hair with a gentle shampoo, then dry thoroughly. A clean, dry base helps the serum absorb without dilution. Checkpoint: your scalp should feel clean and not oily before applying.
2. Fill the glass bottle: Pour your OS-01 HAIR refill into the OS-01 HAIR Glass Bottle and attach the dropper. This keeps application precise and hygienic. Checkpoint: do not overfill; leave room for the dropper.
3. Part and apply: Create part lines and place small drops of serum directly on the scalp, about 1–2 cm apart. Massage gently with fingertips. Checkpoint: aim for the scalp, not the hair strands.
4. Optional dermaroller: If using the OS-01 HAIR Dermaroller, roll gently over the scalp before applying serum. Use light passes in multiple directions. Checkpoint: skip if your scalp is irritated or broken.
5. Let it work: Do not rinse. Leave the serum on the scalp and style as usual after it dries. Use daily for best results. Checkpoint: set a daily reminder to stay consistent.
