Pyunkang Yul Shampoos
Pyunkang Yul built its shampoo line the same way it builds everything else: strip out anything the scalp does not need. Each formula sits close to skin's natural pH so it cleanses without stripping, which matters for anyone dealing with an itchy, tight, or reactive scalp. The ATO Wash and Shampoo Blue Label works as a two-in-one for body and hair, the weakly acidic Scalp Care Shampoo targets sensitive scalps directly, and the Kids and Baby Shampoo Sweet Herb version is mild enough for the youngest members of the household. No heavy fragrance, no aggressive sulfates dominating the ingredient list, just a wash that respects the skin barrier while it cleans.

Pyunkang Yul Shampoo Guide: Low-pH Wash for Sensitive Scalps
Pyunkang Yul's shampoo range grew out of the same minimalist philosophy as its skincare: fewer ingredients, a pH closer to skin's own, and no unnecessary fragrance or foam boosters. The lineup covers everyday hair-and-body wash, a dedicated scalp-care shampoo, and a baby-safe version, so there is a formula for most households rather than one product trying to do everything.
What makes Pyunkang Yul shampoo different
Most shampoos sit on the alkaline side of the pH scale, which lifts the scalp's outer layer along with the dirt and oil it is trying to remove. Pyunkang Yul formulates its washes closer to skin's natural weakly acidic range, so hair and scalp are cleaned without that stripped, tight feeling afterward. It is the same reasoning behind the brand's ATO skincare line, just carried over into hair care.
ATO Wash and Shampoo Blue Label: the two-in-one
The Blue Label ATO Wash and Shampoo is built as a single bottle for both body and hair, which suits anyone who wants to simplify a shower routine or is shopping for sensitive, easily irritated skin. It comes in 290ml, 350ml, and 500ml sizes, so a single traveler or a family sharing one bottle can both find a fit.
Weakly Acidic Scalp Care Shampoo
For a scalp that gets flaky, itchy, or tight after regular shampoo, the dedicated weakly acidic Scalp Care Shampoo is the more targeted pick over the all-purpose ATO wash. It is formulated specifically to calm scalp irritation while still clearing away oil buildup, which is the balance a lot of sensitive-scalp shampoos get wrong by leaning too gentle to actually clean.
Kids and Baby Shampoo Sweet Herb
The Kids and Baby Shampoo Sweet Herb version drops the formula down to what is appropriate for a child's more delicate skin barrier, with a light herbal scent instead of a heavier fragrance load. It is sized at 590ml, built for the wash-every-few-days pace of a family bathroom rather than a single-use travel bottle.
How to use it
Wet hair and scalp thoroughly, work a small amount of shampoo into a light lather focusing on the scalp rather than the lengths, then rinse fully. Because these formulas skip the heavy foam boosters found in many mainstream shampoos, the lather will feel lighter than expected. That is the low-surfactant formula working as intended, not a sign the product needs more product.
Who should reach for this
This line suits anyone with a sensitive or reactive scalp, dry or eczema-prone skin extending down to the hairline, or a household that wants one gentle formula for both kids and adults. It is a reasonable swap for anyone whose current shampoo leaves the scalp feeling tight, itchy, or flaky by the next day.
Pairing with the ATO skincare line
Because the Blue Label wash doubles as a body cleanser, it pairs naturally with the rest of Pyunkang Yul's ATO skincare line for anyone building a full sensitive-skin routine, from face to body to scalp under one low-pH approach.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What's the difference between the Blue Label ATO Wash and the Scalp Care Shampoo?
The Blue Label ATO Wash and Shampoo is a two-in-one for body and hair, meant for everyday use across the whole family. The weakly acidic Scalp Care Shampoo is a hair-only formula built specifically to calm an itchy or irritated scalp, so reach for that one if your scalp is the main concern.
Is the Kids and Baby Shampoo Sweet Herb actually safe for young children?
Yes, it is formulated at a gentler concentration than the adult ATO wash, with a light herbal scent rather than a heavier fragrance. It is meant for children's more delicate skin barrier, though as with any new product it is worth doing a small patch test first if your child has a history of skin reactions.
Why does a low-pH shampoo matter for the scalp?
Skin and scalp sit naturally in a weakly acidic range. Standard shampoos tend to be more alkaline, which can strip the scalp's protective layer along with the dirt they are removing. A low-pH formula cleans while staying closer to that natural range, which is why it tends to leave less of a tight or itchy feeling afterward.
Why does this shampoo lather less than what I'm used to?
These formulas use fewer foam-boosting surfactants than most mainstream shampoos, so a lighter lather is expected rather than a sign you need more product. Focus the amount you use on massaging into the scalp rather than judging by foam volume.
Can I use Pyunkang Yul shampoo every day?
Yes, the low-pH, low-surfactant formulas are designed to be gentle enough for daily washing without the stripped feeling that comes from frequent use of a harsher shampoo. If your scalp is particularly sensitive, the dedicated Scalp Care Shampoo is the better daily pick over the all-purpose ATO wash.
Which size should I buy for a family versus solo use?
The Blue Label ATO Wash comes in 290ml, 350ml, and 500ml, so a solo traveler can pick the smaller size while a shared bathroom is better served by the 500ml. The Kids and Baby Shampoo ships at 590ml, sized for a household's regular rotation rather than single use.
