Pyunkang Yul's Low pH Scalp Treatment is a leave-on scalp serum designed for daily use, delivering calming and supporting actives to the scalp without rinsing off. At $21.84 for 290ml, this is accessibly priced for a scalp treatment; the large size reflects the brand's expectation that you'll use it liberally across multiple weekly applications. The low-pH positioning matters: scalp skin is still skin, and pH-disruptive products cause the same barrier issues on the scalp as on the face.
Scalp care is under-invested territory in most skincare routines. Users who do elaborate facial skincare often ignore scalp health, even though scalp issues (itching, flaking, sensitivity) drive hair quality, shedding rates, and styling product compatibility. Pyunkang Yul's approach applies the same ingredient-quality philosophy to scalp that they use for face, which is unusual in the scalp-care category (dominated by brands with much lower formulation standards).
The leave-on treatment calms scalp inflammation, supports the scalp barrier, and reduces the reactivity that drives itching, flaking, and low-grade shedding. Traditional Korean botanicals deliver calming action, while the low-pH vehicle avoids stripping the scalp's natural acid mantle. Over 4 to 8 weeks of regular use: reduced scalp itch and flaking, less product sensitivity, healthier-looking hair at the follicle due to improved scalp environment.
After shampooing and towel-drying, part the hair in sections and dispense the treatment directly onto the scalp (not the hair length). Massage gently with fingertips for 30 to 60 seconds to distribute. Do not rinse. Style as usual. Use 3 to 4 times per week minimum; daily is fine for reactive scalps.
For intensive repair weeks: combine with the matching brand's shampoo and scalp treatment as a full-routine approach. Scalp skincare works like face skincare: cleansing, treating, maintaining. Single-product scalp approaches are less effective than routine-based care.
Supporting care, not primary treatment. For active hair loss: minoxidil (topical, OTC) or finasteride (oral, prescription) are the clinically-established interventions. This treatment supports the scalp environment that hair grows from, which contributes to retention but doesn't regrow lost hair.
Different products. Some By Mi is a shampoo (rinse-off). Pyunkang Yul is a leave-on treatment. Best combined: shampoo with scalp-focused shampoo, then apply leave-on treatment after. Not redundant; complementary.
Yes, it's applied to scalp rather than hair length. It doesn't affect hair color. In fact, healthier scalp = healthier hair = better color retention indirectly.
No, if applied to scalp only. The watery formulation is not oil-based. Oily scalps should use less product (few drops) to avoid any heaviness.
With 3 to 4 times weekly use: 2 to 3 months. Strong value at this volume and price.
Pair with SOME BY MI Cica Peptide Anti Hair Loss Scalp Shampoo for the matching shampoo, or Dr.FORHAIR Folligen Tonic as a stronger scalp-stimulating alternative.
