Dry Scalp Care: Products and Treatments
This guide provides shopping guidance only—not medical, dermatology, diagnosis, or treatment advice. For persistent scalp issues, consult a licensed healthcare professional.
Understanding Dry Scalp
A dry scalp occurs when the skin on your head doesn't have enough moisture. This can lead to itching, flaking, tightness, and discomfort. While annoying, dry scalp is usually manageable with the right products and habits.
It's important to note that dry scalp is different from dandruff, though they can look similar. Understanding the difference helps you choose the right treatment.
Dry Scalp vs. Dandruff
| Dry Scalp | Dandruff |
|---|---|
| Small, white, dry flakes | Larger, yellowish, oily flakes |
| Scalp feels tight, may be slightly red | Scalp may be oily between flakes |
| Often accompanied by dry skin elsewhere | Not necessarily related to overall skin dryness |
| Worse in dry, cold weather | Can occur year-round |
| Needs moisture | Needs antifungal ingredients |
If you have yellowish, oily flakes, you likely have dandruff and should look for products with zinc pyrithione, ketoconazole, or selenium sulfide. This guide focuses on dry scalp specifically.
Common Causes of Dry Scalp
- Weather: Cold, dry winter air pulls moisture from skin
- Over-washing: Stripping natural oils faster than they replenish
- Harsh shampoos: Sulfates and other strong cleansers can be drying
- Hot water: Strips natural oils from the scalp
- Product buildup: Can prevent natural oils from reaching the scalp
- Dehydration: Not drinking enough water affects skin everywhere
- Age: Skin produces less oil as we get older
- Skin conditions: Eczema, psoriasis, or contact dermatitis
Soothing Ingredients for Dry Scalp
Hyaluronic Acid
The same hydrating ingredient used in skincare works on the scalp too. Draws moisture to the skin. See our hyaluronic acid guide.
Aloe Vera
Classic soothing ingredient that hydrates and calms irritation. Often found in scalp treatments and shampoos.
Glycerin
A humectant that attracts and holds moisture. Common in hydrating hair products.
Natural Oils
- Jojoba oil: Similar to natural sebum; absorbs well
- Argan oil: Rich in vitamin E; nourishing without being heavy
- Coconut oil: Penetrates the hair shaft; can be heavy
- Tea tree oil: Has antimicrobial properties; can be drying in high concentrations
Oat Extract (Colloidal Oatmeal)
Soothes itching and irritation. Often used for sensitive or eczema-prone skin.
Salicylic Acid
Helps remove buildup and dead skin cells, allowing moisture to reach the scalp. Found in clarifying and exfoliating scalp treatments.
Product Categories
Hydrating Shampoos
Look for sulfate-free formulas with moisturizing ingredients. Avoid products that leave your scalp feeling "squeaky clean"—that usually means they're too stripping. Many brands for sensitive skin also work well for dry scalp.
Scalp Treatments and Serums
Leave-on treatments that provide concentrated hydration and relief. Applied directly to the scalp, usually after washing or before bed.
Scalp Oils
Can be used as pre-wash treatments (apply, massage, leave for 20+ minutes, then shampoo) or sparingly as leave-on treatments. Help restore moisture and dissolve buildup.
Scalp Scrubs and Exfoliators
Remove buildup and dead skin cells that can prevent moisture from reaching the scalp. Use occasionally (weekly or bi-weekly), not every wash. Choose gentle formulas if your scalp is irritated.
Scalp Masks
Deep conditioning treatments specifically for the scalp. Leave on for 5-20 minutes, then rinse. Provide intensive moisture and soothing benefits.
Building a Dry Scalp Routine
Weekly Routine
- Pre-wash oil treatment (optional): Apply scalp oil, massage, leave for 20+ minutes
- Gentle shampoo: Sulfate-free, hydrating formula; focus on scalp
- Conditioner: Apply to lengths and ends (not scalp, unless product specifies)
- Leave-on scalp treatment: Apply while hair is damp
Between Washes
- Apply lightweight scalp serum if itching or tightness occurs
- Avoid scratching—it can damage the skin and worsen the problem
Weekly Treatment
- Scalp mask or intensive treatment
- Gentle exfoliation if there's buildup (but skip if scalp is very irritated)
Lifestyle Tips
- Use lukewarm water: Hot water strips natural oils
- Wash less frequently: Try every 2-3 days instead of daily
- Stay hydrated: Drink enough water throughout the day
- Use a humidifier: Adds moisture to dry indoor air
- Protect from harsh weather: Hats in cold, dry weather (choose breathable materials)
- Rinse products thoroughly: Residue can irritate the scalp
- Limit heat styling: Can dry out the scalp as well as hair

Frequently Asked Questions
What's the difference between dry scalp and dandruff?
Dry scalp flakes are smaller and white, caused by lack of moisture. Dandruff flakes are larger, yellowish, and oily, caused by an overgrowth of yeast called Malassezia. Dry scalp is often accompanied by dry hair and skin elsewhere; dandruff is typically oilier.
What causes dry scalp?
Common causes include cold, dry weather, over-washing, harsh shampoos (especially those with sulfates), hot water, product buildup, dehydration, and skin conditions like eczema or psoriasis. Age and certain medications can also contribute.
How often should you wash hair if you have a dry scalp?
Washing too frequently can worsen dry scalp by stripping natural oils. Try washing every 2-3 days (or less frequently) with a gentle, hydrating shampoo. If you exercise daily, you can rinse and condition without shampooing every time.
Do scalp oils help with dryness?
Scalp oils can help, especially as a pre-shampoo treatment. Oils like jojoba, argan, and coconut can provide moisture and help dissolve buildup. Don't apply too much, and make sure to wash out thoroughly to avoid clogging hair follicles.
