What this product is
Written from the ingredient list. Where it describes how a formula behaves, that is inferred from what the ingredients are and where they sit in the list, not measured.
Overview
Low pH Scalp Shampoo is a shampoo from Pyunkang Yul, aimed at fine hair, straight hair and wavy hair. On the evidence of its ingredient list, the formula works on oil control, moisture and scalp soothing. The ingredients doing most of that work are Coco-betaine, Lauryl Glucoside and Disodium Laureth Sulfosuccinate. The list runs to 33 ingredients, 15 of which carry a role we recognise for hair.
How it cleanses
It is sulfate-free: the cleansing is done by Coco-betaine, Lauryl Glucoside and Disodium Laureth Sulfosuccinate, milder surfactants that leave more of the hair's own oil behind.
How it feels on hair
The formula reads as lightweight: humectants lead and there is little in the way of heavy oil or silicone, so it should not weigh fine hair down. There are no silicones in the list. The formula leans to moisture rather than protein.
Protein
There is a small amount of protein in the list: Cysteine.
On the scalp
For the scalp itself the formula carries Menthol, Melaleuca Alternifolia Leaf Oil and Melaleuca Alternifolia Leaf Extract.
Where it goes
It is the first step of a wash: it goes on wet hair before anything else. Apply a moderate amount of the formula throughout the damp hair. Massage gently and rinse thoroughly with lukewarm water.
What it is not for
Nothing in this formula is aimed at protein & strength, volume / lightweight, curl definition and color protection — not a fault, just the shape of what is in the bottle, and the reason one product rarely covers a whole routine. No ingredient here is one we recognise as supporting hair growth. Reducing breakage and growing hair are different things, and this formula's evidence is for the first.
