Why these three?
1) Kérastase Nutritive Bain Satin Riche — Best overall
What it is: Kérastase refreshed the Nutritive line with niacinamide and plant-based proteins to help support the scalp barrier and hair fiber. Bain Satin Riche is the richest cleanser in the range.
What you’ll notice: A plush cream-gel that lathers easily and rinses clean at the roots while leaving mid-lengths flexible and soft. Many users report fewer flyaways and less tugging when brushing. For a more moisturizing formula, it typically won’t flatten hair as much as heavier “buttery” shampoos.
Why it works: Glycerin helps attract moisture, niacinamide supports the scalp’s moisture barrier, and milder surfactants (for example, coco-betaine and sodium cocoyl isethionate) cleanse without the harsh, stripped feeling.
Best for: Medium to coarse hair; very dry, heat- or color-stressed strands; anyone who wants a salon finish.
Good to know: It’s a salon-priced formula, so a little goes a long way. Use a nickel-sized amount and focus on the scalp—let the suds rinse through the lengths. If your roots get flat easily, pair it with a lighter conditioner.
2) Moroccanoil Hydrating Shampoo — Best everyday, color-safe
What it is: A popular daily shampoo that’s sulfate-, phosphate-, and paraben-free. It’s built around glycerin, panthenol, and argan oil for slip and shine.
What you’ll notice: A rich lather that cleans without the squeaky feel, easier detangling in the shower, and smoother hair after blow-drying. Because the cleansing system is gentle, it’s a solid choice for maintaining color.
Why it works: Humectants (like glycerin and panthenol) help hydrate, conditioning polymers and extracts support a smoother feel, and argan oil adds softness without as much heaviness as some oil-forward shampoos.
Best for: Fine to medium hair that’s color-treated or heat-styled and tends to feel dry or frizzy; everyday washing.
Good to know: It has the signature Moroccanoil fragrance. If you’re fragrance-sensitive, consider Aveeno below.
3) Aveeno Scalp Soothing Oat Milk Blend — Best for dry, sensitive scalp (budget)
What it is: A gentle formula featuring colloidal oatmeal, oat extract, and glycerin to help soothe a tight, uncomfortable scalp.
What you’ll notice: Less itch and less “tight” feeling after a few washes, with clean roots that don’t feel stripped. Ends usually feel softer when you follow with a lightweight conditioner.
Why it works: Oat-derived soothing ingredients (including beta-glucans) help calm irritation, and the mild cleanser blend helps avoid over-stripping.
Best for: Sensitive-skin households, kids, pregnancy/postpartum dryness, and anyone who wants a gentler scent.
Good to know: Light fragrance. If your ends are very parched, pair it with a richer conditioner or a weekly mask.
How to pick a shampoo for dry hair and scalp
Look for:
- Humectants: glycerin, propanediol, sorbitol, aloe, hyaluronic acid.
- Barrier helpers: niacinamide, oat/colloidal oatmeal, panthenol, ceramide-like lipids.
- Mild surfactants: coco-betaine, isethionates, sulfosuccinates, amino-based surfactants.
- Light emollients: argan, jojoba, squalane; avoid heavier oils if your roots go flat.
Avoid/limit:
- Frequent use of strong sulfates (SLS/SLES) if you’re already dry.
- High amounts of alcohol denat. near the top of the ingredient list in leave-in products (it’s usually less of a concern in rinse-off formulas).
- Peppermint/menthol if your scalp is reactive; they can feel cooling but may worsen dryness for some people.
How often to wash: Many dry scalps do best with 2–4 shampoos per week. If you sweat or work out often, try rinsing with water and conditioning the ends between full washes.
Routine that makes shampoos work harder
- Pre-rinse: Saturate hair and scalp with lukewarm water for 60–90 seconds to help the shampoo spread evenly.
- Scalp-first cleanse: Use a quarter-sized amount; massage with fingertips (not nails) for 60 seconds. Let the lather rinse through the lengths.
- Condition smartly: Apply conditioner from mid-lengths to ends. If your scalp is truly dry (not oily/flaky), use a small amount of a lightweight conditioner at the roots and rinse well.
- Weekly mask or oil pre-wash: Once a week, apply a few drops of squalane or a conditioning mask to the last two-thirds of your hair for 10–20 minutes before shampooing.
- Style protection: Use a heat protectant and keep hot tools under 400°F/200°C.
- Environmental help: A humidifier in winter can help reduce static and that tight, dry scalp feeling.
When “dryness” is actually dandruff or eczema
Ongoing flakes, redness, or itch can point to seborrheic dermatitis or eczema. If that sounds like you, consider alternating your hydrating shampoo with a medicated shampoo 2–3 times per week, then conditioning the lengths:
- Ketoconazole 1% (e.g., Nizoral A-D) – antifungal; leave on for about 5 minutes.
- Pyrithione zinc 1% – helps with yeast and inflammation (Head & Shoulders Dry Scalp Care is often a gentler option).
- Selenium sulfide 1% – for more stubborn flaking (can be stronger; be cautious with color-treated hair).
See a dermatologist if symptoms last longer than 4 weeks or keep coming back.
Who should pick which?
- Fine hair that needs moisture but hates weight: Moroccanoil Hydrating.
- Very dry, heat- or color-stressed hair plus a tight scalp: Kérastase Bain Satin Riche.
- Sensitive, easily irritated scalp (including kids): Aveeno Oat Milk Blend.
- Curly/coily and parched: Choose one of the shampoos above and add a weekly deep conditioner (or a co-wash on off days, if your scalp tolerates it).
The bottom line
If you want one bottle that hydrates the lengths while keeping roots clean, Kérastase Nutritive Bain Satin Riche is the salon-level pick. For daily, color-safe moisture that won’t feel heavy, Moroccanoil Hydrating Shampoo is a reliable favorite. If scalp sensitivity is the main issue, Aveeno’s Oat Milk Blend is a gentle, affordable option. Add a weekly mask and ease up on high heat, and “dry” hair often starts feeling normal again.

Frequently Asked Questions ▾
Do I need to put conditioner on my scalp?
Usually, no—apply conditioner from mid-lengths to ends. If your scalp is truly dry (and not oily or flaky), you can work a pea-sized amount of a lightweight, scalp-friendly conditioner into your roots and rinse thoroughly.
Can I oil my scalp for dryness?
Yes, lightly. Oils like squalane or jojoba can be helpful as a pre-shampoo treatment. Avoid leaving heavier oils on the scalp, especially if you’re dandruff-prone, since they can trap flakes and may worsen Malassezia-related irritation for some people.
Are shampoo bars good for dry hair?
They can be, but it depends on the bar. Many “soap” bars have a higher pH that can leave hair feeling rough. If you go with a bar, look for a syndet formula (often with ingredients like SCI or isethionates) and follow with conditioner.
Color-treated hair—will these strip dye?
These picks are sulfate-free and commonly used on color-treated hair. To help your color last longer, wash with cooler water when you can and use a conditioning mask weekly.
