Quick answer
Winter hair needs moisture and sealing, in that order. Most routines do one and skip the other.

A winter routine for dry, rough hair has two steps: moisture first, then seal. Condition after every wash (for example with Tresemmé Keratinbond+ Conditioner), use a 15–20 minute hair mask once a week, and while the hair is still slightly damp, smooth a few drops of serum or oil onto the lengths (for example Livon Anti Frizz Serum). Wash no more than 2–3 times a week and skip heat styling where you can. Most routines do one of these steps and skip the other, which is why they do not work.
Moisture first, then seal
Dry hair needs water-based hydration *and* a lipid layer to hold it. A mask alone, or oil alone, only does half the job. Conditioner and masks bring back moisture and softness; a serum or oil then lays a thin coat over the top that stops that moisture escaping into the dry air. Oil on its own just coats dry hair in grease without putting any moisture inside. A mask on its own leaves hair soft for a few hours and straw-like again by evening.
Why hair gets so rough in winter
- Dry air draws water out of the hair, especially at the ends, which are the oldest part of each strand.
- Hot water washes away the natural oils of the scalp and hair.
- Washing too often does the same; the scalp sweats less in winter, so daily washing is not needed.
- Heat styling on hair already dried out by winter is what turns rough into broken.
- Rebonded, straightened or coloured hair is already weaker and turns rough faster in winter.
The winter routine, step by step
1. Wash less, condition every time
Two to three washes a week is enough in winter. Use conditioner at every wash. Shampoo the scalp only, with lukewarm water.
2. A weekly deep mask
Fifteen to twenty minutes on mid-lengths and ends, not the scalp. On mask day, the mask replaces the conditioner. See hair masks.
3. Seal damp, not dry
Press the water out gently with a towel and, while the hair is still slightly damp, apply a few drops of serum or oil. That traps moisture; on dry hair it only coats. See hair serums.
4. Protect from heat
Heat styling on already-dry winter hair is what turns rough into broken. If you need a dryer, use the cool or low setting and hold it away from the hair.

How much to use
- Conditioner: a coin-sized amount for shoulder-length hair, two for long hair. From below the ears to the ends, 2–3 minutes.
- Mask: section the hair and apply section by section so it reaches the ends. Leave 15–20 minutes and rinse thoroughly.
- Serum or oil: two to four drops rubbed between your palms, from mid-length to ends. If hair looks greasy, use less next time.
By hair type
- Fine hair, oily scalp: a light serum on the ends only. Mask no more than once a week.
- Thick or curly hair: more conditioner; on damp hair you can use both serum and oil. Do not brush it dry.
- Rebonded or coloured hair: do not skip the weekly mask, and keep heat to a minimum.
What to watch in a Bangladeshi winter
- Hard water: in some areas the water is high in minerals, which makes hair feel rougher still. Conditioner matters even more there.
- Drying hair in the sun: sitting on the rooftop on a winter afternoon to dry your hair is pleasant, but long hours of strong sun on loose hair add roughness. Move out once it is half dry.
- Load-shedding and the dryer: washing at night and air-drying is kinder to hair anyway; just do not sleep on soaking wet hair.
- Bikes and rickshaws: loose hair tangles in the wind and the ends snap; wear a loose braid for the ride.
Mistakes that make roughness worse
- Using only oil and skipping conditioner.
- Putting mask or conditioner on the scalp, which makes it greasy and can increase flaking.
- Brushing dry, tangled hair hard.
- Twisting a towel around the hair and rubbing hard.
- Buying product after product to "repair" split ends. A split end does not join back together, so trimming is the most effective fix; take a little off every two to three months. More: how to deal with split ends.
When to see a doctor
Ordinary winter roughness does not need a doctor. But if hair suddenly becomes very brittle and breaks in clumps, if there are red, scaly patches, itching or bumps on the scalp, or if it comes with tiredness, weight change or feeling unusually cold, see a doctor; there may be a nutritional or hormonal cause.

Frequently asked questions
Why is my hair so dry and rough in winter?
Dry winter hair needs two things, moisture and a seal to hold it, and most routines do only one. A hair mask alone or oil alone only does half the job. Water-based hydration from conditioner or a mask must be followed by a lipid layer, such as a few drops of serum or oil, to keep that moisture in.
Should I apply hair serum or oil on wet or dry hair?
Apply it on damp hair. A few drops of serum or oil on damp hair traps the moisture that is already there. On completely dry hair it only coats the surface without sealing anything in. So condition, towel off gently, then seal while the hair is still slightly damp.
How long should I leave a hair mask on in winter?
Leave a deep hair mask on for fifteen to twenty minutes, once a week. Apply it to the mid-lengths and ends rather than the scalp, since those are the driest and most damaged parts of the hair. Combined with conditioner at every wash, a weekly mask keeps winter hair softer.
Does heat styling make dry winter hair worse?
Yes. Heat styling on hair that is already dry from winter air is what turns rough hair into broken hair. Cut back on straighteners and hot blow-drying where you can, and protect hair from heat when you do style it. Moisture and sealing only help if you are not undoing them with heat.
Should very dry or curly hair use conditioner every wash day?
Yes, dry or curly hair types lose moisture faster, so a moisturizing conditioner like Tresemme Keratin Smooth Keratinbond+ No.2 Conditioner after every shampoo helps keep the strands soft. Apply it mainly to the lengths and ends rather than the scalp.
Where can I buy an authentic hair serum in Bangladesh?
Buy from a seller who can show the importer's invoice and batch number for the product, such as Livon Anti Frizz Serum for All Hair Types. TheSkinProof is an invoice-verified skincare marketplace where every product is checked against the invoice and batch before it is listed.
