Sound familiar?

Thinning often starts at the scalp

Most hair serums coat the lengths and never reach the roots, where these problems begin.

Hair in the drain

More strands in your brush, on your pillow and in the shower than there used to be.

A wider part

Your part or hairline shows more scalp in photos and under bright light.

Dry, itchy scalp

Tightness, flakes and irritation that leave roots feeling weak.

Korean formulaMarine PDRN + caffeine

Key ingredients

PDRN (salmon-derived) helps condition and soothe the scalp.

Caffeine energises the look of roots and helps reduce breakage-related shedding.

Ginseng and biotin nourish the scalp and strengthen fragile strands.

CICA complex calms dryness and tightness.

Micro-spicules give a gentle tingle and help the serum reach the scalp.

How to use

1. Part clean, dry hair where it looks thinnest.

2. Glide the brush tip along the part so the serum touches the scalp.

3. Massage for 30–60 seconds. Leave in. Use once daily, ideally at night.

Does it tingle?

Yes, a light tingle for a minute or two is normal and comes from the micro-spicules. If you feel burning or see redness that doesn't fade, rinse off and stop using it. Patch-test on your inner arm first if your skin is sensitive.

Questions

Frequently asked

What is PDRN?

PDRN (polydeoxyribonucleotide) is a complex derived from salmon DNA, popular in Korean skincare for conditioning and soothing skin. In Kaelora it's used to care for a dry, stressed scalp.

When will I notice a difference?

Most people notice a calmer scalp within the first few weeks. Hair grows slowly, so give it at least 90 days of daily use to judge the look of fullness.

Can I use it every day?

Yes. It's designed as a once-a-day leave-in. Consistency matters more than the amount you use.

Is it safe for sensitive scalps?

It's made to be gentle, but everyone's skin is different. Patch-test on your inner arm 24 hours before first use. If you're pregnant, breastfeeding or have a scalp condition, check with your doctor first.

Does it work on all hair types?

Yes. Because it's applied directly to the scalp, it works for straight, wavy, curly and coily hair, and it won't weigh your hair down.

How long does one bottle last?

One bottle lasts about a month of daily use. That's why most people choose 2 bottles or Buy 2 Get 1 Free.
