Hair Wash Routine by Hair Type: Stop Copying Influencers
Why a 'one size fits all' hair-wash routine is making your hair worse — wash frequency, conditioner weight and masks matched to your actual hair type, from Reddit.
Editor's note. This is one of five standalone routines we're republishing from Reddit creator u/Jimins_little_minx with her permission. The original post is on r/hygiene. For her full body-care routine in one place, see the hub round-up.
The hair-wash routine you see on TikTok belongs to one person with one specific combination of scalp oil production, hair density, hair porosity, hair length, hair colour treatment status, and styling routine. It's almost never yours. Copying it wholesale is the #1 reason people end up with chronically greasy roots and chronically dry ends — or vice versa.
"I used to watch this girl on TikTok who made like 'one size fits all' kinda hair routine vids. She had dry 3c hair, which you don't actually need to wash as often as someone with finer, oilier or more silky hair type. I was washing my hair once a week and following her expensive-ass aftercare routine and gawd damn was I messing up my scalp. It was not often enough, so shit was just building up and weighing down my hair. Eventually I tried washing my hair twice a week and omg I fixed my hair sooo fast." — u/Jimins_little_minx, r/hygiene
She fixed her hair in days by simply doubling her wash frequency to match her actual hair type (thick, wavy, dry-leaning, waist-length). Her own ends still needed masking every wash; her scalp finally got cleaned often enough to stop building up. That's the whole insight, and it generalises.

Step one: figure out your actual hair type
Most people categorise their hair too generously. You're trying to identify the real combination of variables driving your hair's behaviour, not the aspirational version. There are four axes that matter:
1. Scalp sebum production
This is what drives wash frequency. Independent of hair type. The honest test: how does your scalp feel and look two days after washing, with no product applied?
- Day 2 — already greasy: high sebum production
- Day 2 — fine, day 3 starting to feel oily at the roots: normal sebum production
- Day 3 — still feels clean, no greasiness: low sebum production
- Day 4+ — still completely fine: very low / dry scalp
2. Hair density
How many strands per square inch of scalp. Easier to estimate than measure — pull your hair into a ponytail and feel the thickness of the band:
- Very thin: under 5cm circumference
- Medium: 5–8cm
- Thick: 8–12cm
- Very thick: 12cm+
3. Strand thickness (porosity proxy)
Pull a single shed hair and feel it between your fingertips:
- Fine: almost can't feel it
- Medium: feels like a thread
- Coarse: feels stiff, almost like wire
Fine hair gets weighed down by heavy products; coarse hair needs heavy products to hydrate.
4. Curl pattern
The standard typing — 1 (straight), 2 (wavy), 3 (curly), 4 (coily) — and within each, a, b or c sub-type by tightness of the wave/curl. Curlier hair patterns are inherently drier because sebum has further to travel down the shaft.
Wash frequency by combination
This is the rubric to start from. Adjust based on the results after 2–3 weeks.
Fine, oily/normal scalp, straight or wavy
- Wash: every 1–2 days
- Shampoo: clarifying or balancing, no heavy moisturising shampoos
- Conditioner: lightweight, mid-lengths and ends only — never the scalp
- Masks: rarely, and only on the ends. Heavy masks crush this hair type
- Common mistake: trying to "train" oily scalps by washing less. This rarely works — oily scalps are oily because the sebaceous glands are oily, not because you're "stripping them" by washing.
Medium, normal scalp, wavy
- Wash: every 2–3 days
- Shampoo: balanced sulfate-free or gentle SLS
- Conditioner: medium weight from the ears down
- Masks: once weekly hydrating mask
- Common mistake: copying curly-hair routines (skipping shampoo, co-washing) — wavy hair usually needs more cleansing than 3a/3b curly hair
Thick, normal-to-dry scalp, wavy/curly
- Wash: 2x weekly (her own type)
- Shampoo: gentle, sulfate-free, hydrating
- Conditioner: heavier weight, every time, generously
- Masks: every wash if dry, every other wash if balanced
- Common mistake: copying fine-hair "wash daily" routines — this strips the natural oil this hair type depends on
Coily, dry scalp
- Wash: weekly or co-wash on alternate weeks
- Shampoo: sulfate-free, very gentle; clarifying once a month
- Conditioner: heavy, every wash
- Masks: every wash, deep conditioning
- Leave-ins / oils: essential, daily or every other day
- Common mistake: over-cleansing with sulfate shampoo
What "wash" actually means — technique that matters
The single best technique upgrade most people can make is how they shampoo, not what shampoo they use:
- Wet hair fully before applying shampoo. Properly wet — under the water for at least 30 seconds. Most people apply shampoo to damp hair and get a fraction of the cleansing effect.
- Emulsify shampoo in your hands first with a small amount of water. Apply the lather to the scalp, not the ends.
- Massage the scalp with your fingertips (not nails) for at least 60 seconds. This is where actual cleaning happens.
- Let the lather run down the lengths as you rinse. Don't rub shampoo into the ends — the rinse-down is enough.
- Rinse for longer than feels necessary — about 2x as long as you spent shampooing. Residue is the #1 cause of "I washed my hair and it still feels gross."
- Conditioner on the lengths and ends only. Never on the scalp unless you have a specifically dry scalp that you've confirmed (most "dry scalp" is actually irritation or build-up, not dryness).
- Final rinse with cooler water to flatten the cuticle.
A second shampoo on the same wash is worth doing if you went 4+ days between washes or you used a lot of styling product. The first shampoo lifts the surface dirt; the second cleans the scalp.
Aftercare — masks, oils, leave-ins
This is where most people overspend. The rules:
- Match the mask weight to your hair, not to the marketing. A protein mask on already-protein-overloaded hair causes breakage. A heavy hydration mask on fine hair causes limpness. Read the ingredient list, not the front of the bottle.
- Don't use leave-in conditioner and a serum and an oil and a cream. Pick two. Maximum three for very coily hair. More layers don't help; they just coat.
- Apply leave-ins to damp hair, not soaking-wet hair. Soaking-wet hair dilutes the product.
- Use a microfibre towel or a t-shirt to dry, not a regular towel. Less friction = less frizz, especially for wavy/curly types.

How to know your new routine is working
Give any new routine 3–4 wash cycles (about 2 weeks for most people) before judging. Your scalp adapts to changes — adjusted wash frequency feels weird for the first few washes, then normalises.
The signs you're on the right routine:
- Scalp feels clean for the duration between washes (not greasy by day 2 of a 3-day cycle)
- Hair smells neutral or like your products, not "scalpy"
- No more itchiness or tightness immediately after washing
- Ends look smooth, not straw-like
- Less product needed to style — clean, healthy hair is easier to work with
The signs you've gone too far in the wrong direction:
- Scalp now feels dry, itchy or flaky (washing too often or shampoo too stripping)
- Roots greasy within 24 hours (not washing thoroughly enough; build-up)
- Hair feels weighed down and limp (over-conditioning or wrong-weight products)
- Increased shedding (always check with a dermatologist — could be unrelated to routine)
Frequently Asked Questions
What about "no-poo" or co-washing?
Co-washing (using conditioner instead of shampoo) works well for very coily, very dry hair. It doesn't work for most other types — the cleansing surfactants in conditioner are too mild for normal-to-oily sebum production. If you've tried it and your scalp feels gross, that's the reason. Switch back to a gentle sulfate-free shampoo.
Does washing hair daily damage it?
Not inherently. What damages hair is the wrong wash routine for your type, plus mechanical damage from heat styling, plus chemical damage from colour/relaxing. Daily washing with a gentle shampoo and proper conditioning is fine for oily-scalp hair types. The "wash less" advice was popularised for hair types that genuinely need it (thick, dry, coily) and got generalised to people it doesn't help.
Should I use a clarifying shampoo?
Once every 2–4 weeks if you use a lot of styling product, hard water, or heavy oils. Skip otherwise. Daily clarifying shampoo strips the scalp.
What about scalp scrubs?
Useful 1–2x a month for build-up-prone scalps. Don't use them on the same day as a chemical treatment (clarifying mask, scalp peel). Always follow with conditioner on the lengths.
