Use Sphagnum Botanicals Peat Mud Psoriasis Shampoo at least twice a week, and leave the lather on your scalp for 3–5 minutes before rinsing. During flare-ups, many people do well with 3–4 washes per week for a short period, then step down to 1–2 times weekly for maintenance once symptoms calm. Clinical guidance for medicated/anti-dandruff shampoos often supports multi-minute contact time and 2–3× weekly use, adjusting to hair type and sensitivity.
Why frequency and contact time matter
- Flare routine: 3–4 uses/week for 1–2 weeks
- Control routine: 2–3 uses/week
- Maintenance: 1–2 uses/week (preventive)
Frequency can vary by hair type—some people (especially with oilier, straight hair) tolerate using medicated shampoos more often, while coily/very dry hair may prefer less frequent use.
How to use it (step-by-step)
- Wet hair and scalp thoroughly
- Apply a small amount to the scalp (focus on trouble spots)
- Massage gently for ~30–60 seconds
- Wait 3–5 minutes (let the active ingredients work)
- Rinse thoroughly
- Optional: use a color-safe conditioner on mid-lengths and ends
(General references suggest up to ~5 minutes contact time for medicated shampoos.)
Tips for best results
- Be consistent—regular cadence beats occasional overuse
- Spot-lather itchy or flaky areas
- Pair with a gentle, color-safe conditioner on lengths to avoid dryness
- If you’re using prescription topicals, alternate days or ask your dermatologist how to layer them
- Patch test first; discontinue if irritation occurs
- Safe routine building blocks for those searching Scalp Psoriasis Treatment, dry scalp shampoo, or the best shampoo for itchy scalp
Best Shampoo for Itchy Scalp
If your main issue is itch, look for a gentle, pH-balanced, sulfate-free formula with soothing actives. Sphagnum Botanicals Peat Mud Psoriasis Shampoo checks those boxes, helping reduce buildup and calm irritation while being mindful of hair integrity (including color-treated hair). For many, this makes it a strong everyday choice during control and maintenance phases. (For stubborn cases, dermatology sources sometimes allow more frequent short-term use—always follow label guidance and your clinician’s advice.)
FAQ
Can I use it daily?
Short term during flares—yes, if your scalp tolerates it—but most people thrive at 2–4× weekly, then taper to 1–2× for maintenance. Always listen to your scalp and stylist/dermatologist for personalized advice.
How long should I leave it on?
3–5 minutes before rinsing is a good target to let actives work; many reputable guides endorse several minutes of contact time for medicated shampoos.
Is it safe for color-treated or chemically treated hair?
The formula is gentle, pH-balanced, and SLS/SLES-free, which helps reduce color stripping. For specialty services like keratin, ask your stylist for tailored advice.
