A practical reset routine for reactive, itchy, or burning scalps using fragrance-light pro lines — Medavita, Equave Kids, Alcove, L'Oréal Sensi Balance — with reintroduction protocols and a guide to identifying triggers.
Sensitive scalps need a different approach. Common shampoo ingredients — sulfates, harsh fragrances, certain preservatives — can trigger redness, itching, burning, and flaking even on otherwise healthy skin. The fix isn't medical-grade dermatology shampoo; it's a gentler professional routine built around fragrance-light cleansers, sulfate-free formulas, and microbiome-balancing actives.
ProHair carries the gentle scalp lines that work for reactive skin — Medavita's Italian-formulated Lotion Concentrée and balancing shampoos, Revlon Equave Kids hypoallergenic (popular with adults too), Alcove pre-wash scalp oil, Joico Defy Damage Scalp range, and L'Oréal Sensi Balance. Each product is fragrance-light, sulfate-free where formulated, and chosen for genuinely sensitive scalps — not 'gentle' marketing.
If you've been guessing at what works, this is where to start. Strip back to fragrance-light basics, reintroduce one product at a time, and let your scalp recover.

Product types in your routine
- Fragrance-Light Daily Cleansers — Sulfate-free, hypoallergenic shampoos for daily or every-other-day use without irritation.

Frequently asked questions
What's the difference between sensitive scalp and dandruff?
Dandruff is fungal (Malassezia overgrowth) and produces yellowish, oily flakes plus itch. Sensitive scalp is barrier-function or contact-irritation — redness, burning, itching without flakes. They need different treatments. If you have flakes, see our /collections/dandruff-flake-control page first.
Why is my scalp suddenly sensitive when it never was?
Common triggers: a new shampoo or conditioner, water hardness change, hormonal shifts (postpartum, perimenopause), stress, a new color service, or barrier disruption from over-washing. Strip back to a fragrance-light basic for 4-6 weeks and reintroduce one product at a time.
Are sulfates the main culprit?
Often, yes — SLS and SLES are common triggers for sensitive skin. But not the only one — fragrances, methylisothiazolinone, formaldehyde-releasers, and some essential oils trigger reactions too. Switching to sulfate-free is a good first step but not a complete answer.
Is Equave Kids really safe for adults?
Yes. The 'kids' formulation just means fragrance-light, hypoallergenic, gentle. Many adults with reactive scalps use it long-term. The Equave Volumizing variant is the same gentleness with light volume support.
Can I use Olaplex / bond builders if I have a sensitive scalp?
Generally yes — Olaplex is fragrance-light and rarely a trigger. But if you've reacted to many products, patch-test first. Apply a small amount behind the ear, leave 24 hours, watch for reaction. If clear, proceed.
How long does it take a sensitive scalp to recover?
Usually 4-8 weeks with a stripped-back routine. If symptoms persist beyond 8 weeks of fragrance-free, sulfate-free, gentle care, see a dermatologist — sometimes it's seborrheic dermatitis, contact allergy, or scalp eczema needing prescription treatment.
Should I avoid hair color if I have a sensitive scalp?
Not necessarily. Talk to a stylist about ammonia-free / PPD-free color (Wella Koleston Perfect Me+, Schwarzkopf BlondMe), and always do a 48-hour patch test 24-48 hours before service. If you've had bad reactions, demi-permanent or vegetable color is gentler.
Do you ship discreetly with no fragrance markers?
Yes — products ship in original sealed packaging, no perfumed materials. Free over $99.99 across Canada.
