Scalp Care
The scalp is a unique microenvironment — high sebaceous gland density, constant hair follicle activity, and a microbiome dominated by Malassezia yeasts. Peat is particularly well suited to scalp care because its properties — anti-inflammatory, antimicrobial, adsorptive, mildly keratolytic — address the scalp’s specific needs.
Conditions addressed
Peat-based scalp treatments are relevant to:
- Dandruff — microbiome management and anti-inflammatory
- Seborrhoeic dermatitis — more severe form
- Scalp psoriasis — anti-inflammatory and keratolytic
- Itchy scalp — multiple causes, anti-inflammatory relief
- Oily scalp — sebum adsorption and regulation
- General scalp health maintenance
Products and formats
Peat shampoo. The most accessible format. The peat extract or humic acid is incorporated into a shampoo base and is in contact with the scalp during washing — typically 2–5 minutes. This is a short contact time, but regular use can have cumulative benefit. For best effect, apply the shampoo, massage in, and allow to sit for 2–3 minutes before rinsing.
Peat scalp mask. Applied to the scalp before washing and left for 20–30 minutes. Provides significantly longer contact time than a shampoo and is better suited to addressing active conditions. Used 1–2 times per week as a treatment step.
Peat scalp serum or tonic. A leave-in liquid applied between washes. Less established than the above formats, but growing in popularity. The key question for these products is whether the active concentration is sufficient for benefit without visible residue.
What to look for in a product
Good peat-based scalp products will specify:
- The source and type of peat or extract used
- Complementary actives (zinc, salicylic acid, tea tree)
- pH in the range of 4.5–6.0
Avoid products that simply list “peat” in the ingredient list as a cosmetic flourish with no meaningful concentration.
Professional treatments
At spa and wellness facilities, scalp peat treatments involve applying warm peat directly to the scalp, covering with a thermal wrap, and allowing 30–45 minutes contact time. This is more intensive than any home-use product and closer to the traditional balneological format.
Some trichology clinics incorporate scalp peat masks as part of wider scalp health protocols, particularly for inflammatory conditions.
