Mustard oil, called sarso oil or sarso ka oil in Urdu, is a warming, traditional oil used across Pakistan to nourish the scalp, support thickness and add strength to the hair. It is a rich, strong oil with a distinctive smell, and it works best as a warm pre wash scalp treatment, often blended with a lighter oil to soften its aroma. This guide explains the benefits of mustard oil for hair, how to use it safely, and how it fits into a natural routine. To compare it with other oils, read our complete guide to hair oils and best hair oil in Pakistan.
What is mustard oil (sarso oil)?
Mustard oil is pressed from mustard seeds, and in Pakistan it is a deeply traditional oil known as sarso oil or sarso ka oil. It has been used in homes for generations not only for cooking but also for hair and body massage. It is a rich oil with a strong, sharp smell and a natural warming quality on the skin. That warmth is a big part of its appeal, as many people feel it stimulates the scalp during a massage. Because the smell is strong, it is common to mix sarso oil with a milder oil like coconut or almond for a more pleasant treatment.
Benefits of mustard oil for hair
Used as a regular scalp treatment, sarso oil offers several traditional benefits valued in Pakistani hair care.
- Warms and stimulates the scalp, which many feel supports healthy growth.
- Rich in fatty acids that nourish and condition dry hair.
- A traditional remedy believed to support thickness and strength.
- Coats and protects the hair, helping reduce dryness.
- Doubles as a warming body and scalp massage oil.

Does mustard oil help hair growth?
Mustard oil is a long trusted traditional remedy rather than a heavily studied modern treatment. Its supporters point to its warming effect and its nourishing fatty acids, which help create a healthy scalp environment, and a healthy scalp is the foundation for good growth. Combined with regular massage, which itself boosts blood flow to the roots, sarso oil can be a helpful part of a growth routine. It is best viewed as a nourishing, strengthening oil rather than a guaranteed cure. You can browse related research through the United States National Library of Medicine at PubMed.
How to use mustard oil for hair
Sarso oil is strong, so a warm, diluted pre wash treatment is the best way to enjoy it.
- Mix mustard oil with an equal part of a milder oil like coconut or almond to soften the smell.
- Warm the blend gently until it is comfortably warm, not hot.
- Massage it into the scalp for a few minutes, then work it through the lengths.
- Leave it on for thirty to sixty minutes.
- Wash out well with a gentle shampoo, using two light washes if needed.
Mustard oil for the scalp and dandruff
The warming, nourishing nature of sarso oil makes it a traditional choice for a dry, flaky scalp. A warm massage helps loosen flakes and moisturise the skin, and many people find it soothing in the cooler months. If your scalp is very flaky, adding a couple of drops of tea tree oil to the blend can boost its clarifying effect. As with any strong oil, keep the amount modest and always wash it out thoroughly so the scalp stays fresh and clean.
Mustard oil for different hair types
Dry and thick hair
Dry, thick and coarse hair handles sarso oil well, since it can take a rich, warming treatment that seals in moisture and tames roughness.
Fine or oily hair
If your hair is fine or your scalp is oily, use only a small, well diluted amount and keep it mainly on the scalp for the massage, washing it out fully so the hair does not feel heavy.
Choosing a good mustard oil
For hair care, look for pure, cold pressed mustard oil (often labelled kachi ghani), which keeps more of its natural goodness than heavily refined oil. A genuine sarso oil has a strong, sharp aroma and a deep golden colour. Buy a sensible bottle size, store it tightly closed in a cool, dark place, and use it within a few months so it stays fresh.
Mustard oil price in Pakistan and where to buy
Mustard oil is one of the most affordable and easily available oils in Pakistan, found in almost every local store. For hair care, choosing a clean, cold pressed grade is worth the small extra cost. To explore gentler, ready made hair oil blends with free delivery and cash on delivery, see the Dalouk range on our best hair oil in Pakistan guide, or start with the popular Dalouk Onion Hair Oil.
Precautions and safety
Mustard oil is strong, so a few precautions help. Always do a patch test before the first use, since some people find pure mustard oil too harsh for the skin. Dilute it with a milder oil, keep it away from the eyes, and never leave it on for days at a time. Warm it gently rather than heating it until it is hot. If you feel any burning or notice redness, rinse it out and use a smaller, more diluted amount next time. To read more about the oil, see the mustard oil page on Wikipedia.
Can you mix mustard oil with other oils
Yes, and mixing is the recommended way to enjoy sarso oil. On its own the smell is strong and the oil is heavy, so blending it with a lighter, milder oil makes the treatment far more pleasant. A popular combination is equal parts mustard and coconut oil, which softens the aroma while adding coconut deep conditioning. Some people also add a few drops of a fragrant essential oil, or blend in a little almond oil for extra softness. Mixing not only improves the smell and feel but also makes the oil easier to spread evenly and easier to wash out afterwards.
Mustard oil for a warming scalp and body massage
One of the most loved traditional uses of sarso oil is a warming massage. Gently warmed mustard oil feels soothing on the scalp and body, especially in the cooler months, and the massage itself boosts blood flow, helps you relax and eases tension. Many families in Pakistan use it as a comforting winter ritual for both hair and tired muscles. For the hair, focus the warm massage on the scalp for a few minutes before working the oil through the lengths, then leave it to nourish before washing.
Mustard oil compared with onion and coconut oil
Each of these oils plays a different role. Mustard oil is a warming, traditional scalp oil valued for stimulation and nourishment. Coconut oil is a gentle sealing oil that soaks into the strand and is the best all round conditioner. Onion oil is a lighter blend aimed directly at growth and hair fall. Many people combine their strengths, using a warm mustard massage in winter, coconut as a regular conditioning treatment, and an onion hair oil through the week for growth. Our complete guide to hair oils shows how they all fit together.
Who should be careful with mustard oil
Because it is a strong oil, mustard oil is not for everyone. People with sensitive skin, very fine hair or an oily, acne prone scalp may find it too heavy or harsh, and should either dilute it well or choose a gentler oil. Anyone with a known allergy to mustard should avoid it. A simple patch test on the inner arm a day before the first use tells you quickly whether your skin is comfortable with it. When in doubt, a milder oil such as almond or coconut is an easy, gentle alternative.
Signs your mustard oil routine is working
With regular warm massages, the first thing many people notice is a calmer, less dry scalp and hair that feels stronger and more nourished. Over several weeks the hair often looks fuller and healthier as breakage reduces. Because mustard oil is a traditional, supportive treatment rather than a fast acting product, the changes are gradual, so taking a photo at the start and again after two months is the best way to judge real progress.
Common mistakes to avoid with mustard oil
- Using it undiluted, which can feel too strong and harsh on the skin.
- Heating it until it is hot rather than gently warm.
- Leaving the strong smelling oil on for days instead of washing it out the same day.
- Skipping the patch test before the first use.
- Using too much, which leaves a heavy film that is hard to rinse out.
Fitting mustard oil into your weekly routine
Sarso oil works best as a once weekly warm treatment rather than a daily oil. Pick an evening when you can relax, warm a diluted blend, give yourself a gentle scalp massage, leave it in for an hour, and wash it out well. In winter you might use it a little more often for its comforting warmth, and in summer you can switch to a lighter oil. Kept as a simple weekly ritual, mustard oil is an affordable, traditional way to care for the scalp and strengthen the hair.
Setting realistic expectations with mustard oil
Mustard oil is a nourishing, warming traditional treatment, not an instant growth cure. It supports a healthy scalp, conditions the hair and, through regular massage, helps create good conditions for growth. It will not regrow hair on a bald area or transform thin hair overnight. Treated as one steady part of a wider routine that includes gentle washing, a balanced diet and enough rest, sarso oil can be a comforting and useful addition to your hair care, especially in the cooler months.
