cool salt and menthol

Panthenol converts to pantothenic acid (vitamin B5) inside the skin, where it plays a role in coenzyme A synthesis, essential for skin barrier repair. It hydrates not by sitting on the surface, but by integrating into the lipid bilayer and attracting water molecules from deeper layers. In DR.G DOOPI LAB COOL SALT LONG's hair, Panthenol (Vitamin B5) targets loss of firmness, delivering supports visible firmness and a lifted, contoured appearance with consistent use.

Panthenol (Vitamin B5)
penetrates deep to hydrate from within and repair compromised barrier tissue
Biotin
strengthens keratin infrastructure from the inside to reduce breakage and promote thickness
Tocopherol (Vitamin E)

Ingredients

cool salt, menthol help cool and refresh the scalp without a heavy residue.

Leave-in scalp tonics are most useful when they refresh the scalp between washes without leaving residue at the roots. Dr.G Doopi Lab Cool Salt Long-lasting Cooling Tonic 100ml follows that logic with cool salt, menthol, helping overheated or oily areas feel cooler and more manageable through the day. That matters because irritation and excess sebum often return faster than a full wash routine can. A lightweight tonic gives users a way to address those moments directly instead of waiting until the next shampoo. Cooling support can reduce the urge to scratch, while scalp-freshening ingredients help the roots feel cleaner and less heavy. In practical terms, the result is not regrowth or a medical treatment claim, but a better-maintained scalp environment with less discomfort and less midday heaviness. The science story is fast scalp refresh plus leave-in comfort: support the root area without flattening hair or forcing another full wash.
