Why Does My Hair Get So Oily?
Understanding the cause of your oily hair is the first step toward managing it. The grease you see isn’t coming from your hair strands themselves; it’s produced by sebaceous glands in your scalp. These glands secrete a natural oil called sebum. Sebum is essential for keeping your scalp and hair moisturized and protected. However, when these glands go into overdrive, you end up with an excess that leads to oily hair.
Several factors can contribute to an overproduction of sebum:
- Genetics: Your genetic makeup is the biggest determinant of how much oil your scalp produces. If your parents have oily hair, you are more likely to have it too.
- Hormonal Fluctuations: Hormones, particularly androgens, play a significant role in sebum production. Changes during puberty, menstruation, pregnancy, or due to stress can cause a spike in oiliness.
- Over-Washing: It sounds counterintuitive, but washing your hair too often with harsh shampoos can strip your scalp of its natural oils. In response, your scalp may overcompensate by producing even more sebum to replace what was lost.
- Product Buildup: Using heavy conditioners, styling creams, or serums can create buildup on your scalp. This residue can trap oil and make your hair appear greasier than it is.
- Hair Type: People with fine, straight hair often notice oiliness more quickly. The sebum can easily travel down the straight hair shaft, whereas curls and coils can slow its distribution.
What to Look for in a Drugstore Shampoo for Oily Hair
When you’re standing in the shampoo aisle, the sheer number of options can be overwhelming. To cut through the noise, focus on the ingredient list and the product’s description.
Key Ingredients That Help
- Clarifying Agents: Look for shampoos labeled “clarifying” or “purifying.” These are formulated to give your hair a deep clean. Ingredients like apple cider vinegar and tea tree oil are excellent natural clarifiers that help remove buildup and balance the scalp’s pH.
- Gentle Surfactants: Surfactants are the cleansing agents in shampoo. While strong sulfates like Sodium Lauryl Sulfate (SLS) can be effective, they can also be too harsh and trigger more oil production. Look for gentler alternatives like Sodium Laureth Sulfate (SLES) or sulfate-free cleansers such as Cocamidopropyl Betaine.
- Salicylic Acid: Often found in skincare, salicylic acid is a fantastic exfoliant for the scalp. It helps break down dead skin cells and excess oil, preventing clogged follicles and reducing greasiness.
- Niacinamide: This form of vitamin B3 helps regulate oil production and improves the health of your scalp’s moisture barrier.
- Clay (Kaolin or Bentonite): Clays are highly absorbent and work like a magnet to draw out impurities and excess oil from the scalp and hair without being overly drying.
Ingredients to Avoid
- Heavy Silicones: While some silicones can be beneficial for smoothing hair, heavy ones like dimethicone can build up on the hair, weigh it down, and trap oil at the scalp.
- Thick Oils and Butters: Shampoos with heavy moisturizing ingredients like coconut oil, shea butter, or argan oil listed high on the ingredient list are generally better suited for dry hair types. These can be too heavy for an oily scalp.
- Harsh Sulfates: As mentioned, potent sulfates can lead to the over-drying and over-production cycle of oil. If your scalp is sensitive, it’s best to steer clear.

Frequently Asked Questions (FAQ)
Q: How often should I wash oily hair?
A: There is no one-size-fits-all answer. It depends on your genetics, lifestyle, and hair type. A good starting point is every other day. If your hair feels greasy daily, washing it every day with a gentle, non-stripping shampoo is perfectly fine. The myth that washing daily “trains” your hair to be oilier is largely untrue if you’re using the right products.
Q: Is it safe to use a clarifying shampoo every day?
A: It’s generally not recommended to use a strong clarifying shampoo, like the Neutrogena Anti-Residue, every day. These are formulated for a deep clean and can be too drying for daily use. A good routine is to use a gentle daily shampoo for regular washes and a clarifying shampoo once a week or a couple of times a month to remove stubborn buildup.
Q: My roots are oily, but my ends are dry. What should I do?
A: This is a very common issue. Use a shampoo specifically formulated for oily roots, like the L’Oréal Elvive Extraordinary Clay. When you wash, concentrate the shampoo on your scalp where the oil is. When you condition, apply the product only from the mid-lengths to the ends, avoiding the root area entirely. This gives your ends the moisture they need without weighing down your scalp.
Q: Does dry shampoo make oily hair worse?
A: Dry shampoo is a great tool for absorbing oil and extending the time between washes. However, it doesn’t actually clean your hair. Overusing it can lead to scalp buildup, which can clog follicles and potentially worsen scalp issues. Use it for a day or two, but make sure to wash your hair thoroughly with a good shampoo to remove all the residue.
Q: Can my diet affect how oily my hair is?
A: Yes, your diet can influence sebum production. Diets high in sugar, refined carbohydrates, and unhealthy fats can sometimes trigger an increase in oil production. Staying hydrated and eating a balanced diet rich in fruits, vegetables, and healthy fats can contribute to better scalp health overall.
