• Shampoo is built for the scalp, which produces more sebum than facial skin and is covered in dense hair. Its surfactant load is higher than facial skin wants, and applied daily to a face it strips and irritates.
• Face wash is built for skin, and it is not designed to get through and rinse out of coarse hair. It leaves residue at the roots.
• Body wash and bar soap are worse than either — often alkaline, often heavily surfactant-loaded, and a fast route to a dry, brittle beard and a flaking face.

A beard wash sits between them: a milder surfactant system than shampoo, with more conditioning agents, at skin pH, and designed to rinse cleanly from coarse hair.

Class	Doing what	Names
Mild surfactant	Cleans without stripping	Coco-glucoside, sodium cocoyl isethionate, cocamidopropyl betaine
Conditioning polymer	Reduces friction; deposits on rinsing	Polyquaternium-10, guar hydroxypropyltrimonium chloride
Emollient	Softness	Glycerin, panthenol, light oils
Preservative	Essential	Phenoxyethanol, sodium benzoate

Two or three times a week for most beards, not daily. Beard hair receives little sebum along its length, and daily surfactant removes what does reach it. Rinsing with water on the other days is enough for most people.

Very oily skin, heavy physical work or a smoky environment shift that toward more frequent washing; a long beard in a dry climate shifts it toward less.

Get to the skin. The most common mistake is washing the surface of the beard and never reaching the face underneath, which is where sebum, dead skin and product accumulate — and where the itching and flaking come from.

Fingertips, against the grain, at the roots, for thirty seconds. Rinse thoroughly, and longer than feels necessary; residue at the roots is itself a cause of itching. Pat dry, then Beard Oil onto a damp beard.

If flaking persists despite proper washing and oiling, it is very likely seborrhoeic dermatitis — Malassezia metabolising sebum in a warm covered environment. The treatment is an antifungal: pyrithione zinc, ketoconazole 1% or selenium sulfide shampoo, used on the beard once or twice a week and left on for a few minutes.

That is an OTC drug, not a cosmetic beard wash, and it is the step that resolves what most beard-care routines never touch.

Cosmetic in the US — FDA primary category (13) shaving preparations, overlapping with (06) hair preparations (non-coloring) and (12) personal cleanliness. No monograph applies.

It becomes an OTC drug with an antidandruff claim and a monograph active, or with an antibacterial or acne claim. FDA's 2016 rule banned nineteen ingredients, including triclosan, from consumer antiseptic washes.

In the EU, preservatives come from the Annex V closed positive list of 60 entries, methylisothiazolinone is capped at 15 ppm in rinse-off products, and zinc pyrithione has been prohibited in EU cosmetics since 2022 following its CMR classification — which is why European antidandruff options differ from American ones.

12–18 months after opening. A surfactant product in a shower is reasonably robust.

Separation, thinning, cloudiness or a change in smell ends the bottle — and, as ever, never top it up with water, which contaminates the remainder.
