What happens to your scalp during chemotherapy?

Your scalp is more vulnerable than it appears. When you undergo chemotherapy (the use of cytotoxic drugs to treat cancer), your hair follicles and the surrounding scalp skin, both of which are made up of rapidly dividing cells, can be affected. The result may be tenderness, itchiness, rough or flaky skin, and hair that thins or falls out.¹²

Specifically, hair loss on the scalp often begins 2 to 4 weeks after starting chemotherapy.² Your scalp may also feel tender or sensitive.¹† Over time, the scalp barrier (the protective layer of the skin) can become compromised: it may dry out, lose its natural oils, and become more prone to irritation.

If you already have a sensitive scalp (sometimes called “sensitive scalp condition” or SSC), characterised by tingling, burning, itching or intolerance of many skincare or haircare products, the effect of chemotherapy compounds the challenge.³

This article will guide you gently, step by step, through creating a wash-day routine that treats your scalp with care, minimises irritation, and gives you actionable tools you can use now, whether hair loss is present or not.


Why ultra gentle cleansing matters for a sensitive or post chemo scalp

When your scalp is recovering or compromised, even routine cleansing can become a source of irritation. Studies show that people with SSC should prioritise mild surfactants (the cleaning agents) and avoid frequent contact with harsh chemical treatments.³

In the context of chemotherapy affected scalps, guidelines from credible cancer care organisations emphasise “gentle hair products such as baby shampoos or products made for sensitive skin.”¹† That means avoiding heavy fragrances, sulfates, strong conditioners applied directly to the scalp, hot styling tools, and chemical treatments (perms, colouring) until the scalp barrier is restored.³

Tip: Think of your scalp as delicate skin. Would you use a harsh soap on your face if it were inflamed? Probably not. Apply the same logic to your scalp right now.


Building your ultra gentle wash day routine

The following routine is designed for sensitive, treatment affected scalps. It assumes you are using a gentle shampoo like the Sensitive Scalp Shampoo and a fragrance free conditioner such as the Sensitive Scalp Conditioner from The Better Scalp Company.


Step 1: Pre wash preparation

  • Choose a lukewarm water temperature (not hot). Hot water may increase scalp sensitivity and redness.

  • Detangle gently if you have hair; use a wide tooth comb. Don’t tug or pull.

  • If you’re wearing a wig or head covering, take it off for a few minutes before washing so the scalp can breathe.


Step 2: Shampooing

  • Apply a small amount of Sensitive Scalp Shampoo to your scalp, focusing on the roots and skin rather than only the hair length.

  • Gently massage using your fingertips in circular motions (avoid nails). The goal is to stimulate blood flow without irritating.

  • Rinse thoroughly, ensuring no residue remains. Residual product can irritate the barrier.

  • Frequency: For very sensitive scalps, every other wash day (or even every 2–3 days) may be enough. Over washing can strip protective oils and increase irritation.³


Step 3: Conditioning

  • After rinsing shampoo, apply the Sensitive Scalp Conditioner mainly to the hair lengths, not directly onto the scalp unless instructed by your provider.

  • Leave for 1–2 minutes, then rinse carefully.

  • If your scalp feels especially dry, you may apply a tiny amount of conditioner to the very edges (temple or forehead area) but avoid layering heavy products directly on the scalp skin.


Step 4: Post wash scalp care and protection

  • Pat your hair and scalp gently with a soft towel, no vigorous rubbing.

  • If your scalp is exposed (e.g., after hair loss), apply a broad spectrum sunscreen SPF 30+ or wear a wide brim hat when outdoors.⁴

  • Consider using a silk or satin pillowcase and natural fibre hats or scarves to avoid friction and synthetic fabric irritation.⁵

  • If itch or burning persists, talk with your dermatologist or oncologist; they may recommend a light, fragrance free scalp serum.


Step 5: Styling and protective measures

  • Avoid chemical treatments (colouring, perming, bleaching) until your scalp barrier feels resilient again.³

  • Avoid high heat styling tools on the scalp or roots.

  • When wearing a head covering or wig, remove it nightly or when possible so the scalp can breathe and any sweat or build up can be cleaned.


Table: Concern → Routine → Kit Size → Refill Interval

Concern Routine Bundle size suggestion Refill interval
Scalp feels tender / starting chemo Gentle shampoo + light conditioner; avoid styling chemicals 240 mL shampoo + 240 mL conditioner Every 6 weeks
Hair thinning and scalp visible Gentle shampoo + light conditioner; avoid styling chemicals; protect scalp from sun Keep same size; add sunscreen mist Every 6 weeks + mist refill every 3–4 weeks
Post hair loss (scalp exposed) Use shampoo and daily sun protection; soft fabrics 240 mL shampoo + sunscreen mist Shampoo/conditioner every 6 weeks; mist refill every 4 weeks
Hair regrowth begins Maintain gentle routine; gradually introduce full length hair wholesome conditioning 240 mL shampoo + 240 mL conditioner Every 6 weeks

Bundle size and refill interval are suggestions; adjust based on your usage and product supply in your region.


Why the Sensitive Scalp Shampoo and Conditioner matter

Using a specifically designed sensitive scalp shampoo helps because research on SSC shows that mild surfactants and low irritancy formulas reduce barrier disruption and sensory symptoms (tingling, burning, itch) more effectively than standard shampoos.³

In the context of chemotherapy affected scalps, guidance emphasizes “gentle hair products … made for sensitive skin.”¹† By choosing the Better Scalp Company’s sensitive scalp range, you align with both sensitive scalp research and oncology scalp care advice.


When should you see a dermatologist?

Even with the best home routine, it is wise to consult a certified dermatologist if:

  • Your scalp develops open sores, persistent bleeding, or signs of infection (redness, warmth, pus).

  • Your hair loss is patchy in an unusual pattern, not just diffuse thinning. The American Academy of Dermatology recommends a dermatologist for diagnosis of hair loss causes.⁶

  • The scalp pain, burning or itch is severe or worsening, interfering with sleep or daily life.

  • You are considering restarting chemical treatments (colour or perms) before your oncologist or dermatologist advises it.

Your dermatologist can assess whether there is an underlying scalp condition (seborrhoeic dermatitis, psoriasis, folliculitis) that requires treatment in addition to your gentle routine.


Common myths and misconceptions

  • Myth: “If I stop washing my scalp while undergoing chemo, I will lose less hair.”
    Reality: While you might feel like skipping shampoo protects the scalp, not cleansing regularly can lead to build up, sweat, oils and increased irritation, which can worsen scalp comfort and barrier health.⁵

  • Myth: “Once my hair is gone I don’t need to worry about the scalp anymore.”
    Reality: A bare scalp still needs protection, cleansing and moisturising like any facial skin. It is exposed and can be affected by sun, friction, dryness and irritation.⁵

  • Myth: “Fragrance free means boring, therefore less effective.”
    Reality: For sensitive or treatment affected scalps, avoiding fragrance (a common irritant) is a smart choice. The absence of fragrance does not mean less effective; it means safer for the barrier.


Measuring progress and what to expect

  • You may notice scalp tenderness decreasing after a few wash routines (2–4 weeks) if you maintain the gentle protocol.

  • Hair regrowth, if applicable, generally begins 3 to 6 months after chemotherapy ends.²

  • If you are using the Table above, track your “refill interval” to ensure you never run out of the gentle shampoo or conditioner. Consistency matters.

  • Note improvements in scalp comfort (less tingling or itching) and visually reduced signs of dryness or redness.


Final encouragement

Your scalp has been through an extraordinary journey. It deserves your care, gentleness and patience. Following a thoughtful, ultra gentle wash day routine like the one outlined here gives you concrete, empowering steps to support your scalp’s health. Remember: you are not alone in this. If something doesn’t feel right or the symptoms linger, your dermatologist and healthcare team are your allies. With time, kind care and consistency, your scalp can find its way back to a calmer, stronger state.
