An itchy scalp with hair shedding usually signals irritation or inflammation, not simple dryness. First steps: stop new hair products, switch to gentle lukewarm washing, and try a medicated shampoo containing ketoconazole, zinc pyrithione, or selenium sulfide. Seek medical care fast for patchy bald spots, painful scaling, oozing, fever, or symptoms lasting over two weeks.

# What To Do If Your Scalp Is Itchy And Hair Is Falling Out

## Why Do Itching and Hair Shedding Happen Together?

An irritated scalp barrier triggers scratching, and scratching increases inflammation. That inflammation can push more hairs into shedding, while the physical act of scratching snaps hairs and makes hair loss look worse than it is. Most underlying causes are treatable once identified.

## What Causes an Itchy Scalp With Hair Loss?

Several distinct conditions can produce this combination, and each needs a different treatment approach.

- **Seborrheic dermatitis (dandruff/scalp eczema):** greasy or yellowish flakes with itch, driven by yeast overgrowth
- **Contact dermatitis:** reaction to shampoo, dye, fragrance, or styling products
- **Scalp psoriasis:** thick, scaly plaques with intense itch
- **Tinea capitis (scalp ringworm):** scaly patches with broken hairs or bald areas, fungal
- **Lice:** severe itch, especially behind the ears or at the nape
- **Dryness and over-cleansing:** hot water and harsh shampoos stripping natural oils
- **Telogen effluvium (stress-related shedding):** a stressor pushes hairs into the shedding phase, scalp may feel tender

## What Can You Do at Home Right Now?

If symptoms are mild and you feel otherwise well, a few low-risk steps can calm the scalp while you arrange care. Skip self-treatment and get medical advice if you have open sores, pus, or a rapidly spreading rash.

- **Pause triggers:** stop any shampoo, serum, or dye started in the past 2-4 weeks; avoid tight braids and heavy extensions
- **Wash gently:** lukewarm water, fragrance-free shampoo, fingertip massage instead of nails; try every other day for a week
- **Use a medicated anti-dandruff shampoo:** ketoconazole, zinc pyrithione, selenium sulfide, or salicylic acid, applied to the scalp and left on for several minutes, 2-3 times weekly for 2-4 weeks
- **Soothe without clogging:** a light, fragrance-free moisturizer or a few drops of non-comedogenic oil; patch test first

## What Does a Dermatologist Check For?

A clinician evaluates the pattern of loss, diffuse shedding versus patchy bald spots, and examines the scalp condition directly. They may use a dermatoscope, perform a gentle pull test, or take a scalp swab or scraping if infection is suspected. Blood tests can rule out iron deficiency, thyroid disease, or vitamin D deficiency in some cases.

## How Is Each Cause Treated?

Treatment depends entirely on the underlying diagnosis, which is why identifying the cause matters more than generic scalp care.

- **Seborrheic dermatitis:** antifungal medicated shampoo (ketoconazole); short prescription anti-inflammatory course for flares
- **Contact dermatitis:** remove the trigger; short topical anti-inflammatory course; patch testing for repeat reactions
- **Scalp psoriasis:** medicated shampoos plus prescription topical therapy; hair regrows once inflammation is controlled
- **Tinea capitis:** prescription oral antifungal medicine, since topical shampoo alone rarely clears infection in the hair shaft
- **Lice:** over-the-counter treatment with correct timing and combing; wash bedding and hats
- **Telogen effluvium:** gentle scalp care, adequate protein intake, and sleep consistency; recovery can take several months

## When Should You Seek Medical Care?

Book an appointment if itch lasts longer than two weeks, if shedding is sudden or severe, or if bald patches appear. Get urgent care for fever, pus, spreading redness, severe pain, or a rapidly enlarging tender lump on the scalp.

## Key Facts

- **Condition type:** dermatological (scalp), not a hair transplant procedure
- **Most common triggers:** new hair products, dye, harsh shampoo, hot water, stress
- **Home-treatment window:** 2-4 weeks with medicated shampoo before reassessment
- **Medicated shampoo actives:** ketoconazole, zinc pyrithione, selenium sulfide, salicylic acid
