Black Blend Complex That Nourishes Scalp and Hair

A blend of black rice extract, black bean extract, and black sesame extract delivers moisture and nutrition to the scalp while adding shine to hair. Brewer's yeast extract energizes hair roots, and caffeine revitalizes the scalp to support stronger, healthier hair. Free from 20 potentially irritating ingredients, including 4 types of sulfate surfactants. Recommended for those concerned with hair loss, crown odor, scalp itchiness, or dandruff.

Scalp care starts with a cleansing shampoo

Just like facial skin, your scalp needs daily cleansing to remove built-up sebum and impurities and stay healthy. This shampoo is a functional cosmetic reported to the Ministry of Food and Drug Safety for helping to relieve hair loss symptoms. It works to balance the scalp environment while caring for hair roots. If you're using a conditioner or scalp tonic, apply them after thoroughly cleansing with this shampoo.

Evening wash to clear the day's buildup

It's best for scalp health to wash away the day's accumulated sebum, dust, and styling residue in the evening. If you feel you need a morning wash too, a light rinse is enough. Formulated at a mildly acidic pH (4.8–5.8), it's gentle enough for daily use without stressing the scalp, and suitable even for sensitized scalps.

3-minute massage, focusing on the crown

Wet your scalp and hair thoroughly with warm water, then dispense an appropriate amount into your palm and work into a rich lather. Apply the foam to your crown and entire scalp, then gently massage with your fingertips for about 3 minutes. Pay extra attention to areas with higher sebum production, like the crown and hairline, then rinse thoroughly with lukewarm water until no foam remains.

Recommended combinations by scalp concern

• If you're dealing with oily scalp and scalp odor around the crown: Follow up with a scalp-specific tonic to balance oil and moisture levels
• If your hair feels limp and lacks volume: Apply conditioner only from mid-lengths to ends to preserve root lift
• If your scalp is dry and sensitive: Use a soothing scalp essence 2–3 times a week to help maintain scalp condition

Precautions and storage

Failing to rinse thoroughly after shampooing can actually lead to scalp troubles or contribute to hair loss, so make sure to wash away all foam completely. If product gets into your eyes, rinse immediately with water. If you have any wounds on your scalp, or experience redness, itching, or other adverse reactions, discontinue use and consult a dermatologist. Store in a cool place away from direct sunlight and keep out of reach of children.
