9 Greasy Hair Causes You Never Considered, But Could Be The Reason Your Roots Are Oily

Few things are worse than waking up the morning after washing your hair or drying it after a shower and discovering it's still greasy. While this totally sucks, the greasy hair causes you never considered below could help you figure out what to change in your beauty routine to avoid continually annoying greasy roots. I promise you won't be stuck with greasy roots forever!

Generally speaking, my hair slants toward the dry side. However, there were a few months last winter I could just not control the greasiness. I gradually reached for stronger and stronger shampoos thinking that would solve the problem, but things were just getting worse. Per my stylist pal's advice, I decided to just totally hit the "reset" button on my head for two weeks and only wash my hair with baby shampoo. Luckily, I noticed a marked difference and things slowly went back to normal! My friend suspected that the harsh shampoos were over-stripping my natural oils and causing my scalp to produce even more oils, which is why letting it rebalance was completely crucial.

Beyond the possible causes of greasy hair below, definitely don't hesitate to reach out to your doctor if you're really concerned. A dermatologist will likely be able to get to the root (ha) of your problem faster than you otherwise would on your own. Good luck!

1. Humid Weather

If you live somewhere with humidity, there's unfortunately not much you can do during the summer months other than master all the ways to make your hair less greasy!

2. Touching Your Hair Too Much

Your hands produce oil that can easily get in your hair if you're constantly playing with it. When you're finished styling your hair each day, try to leave it alone!

3. Using Shine Serums

Shine serums add even more oil to your head than you naturally produce. If you're trying to fight frizzy and oily hair at the same time, consider using an anti-frizz conditioner or deep conditioning mask instead of shine serums.

4. Over-Conditioning

How can you tell you're going overboard on conditioner? Beautylish explained, "You know you've over-conditioned when your hair feels too soft and limp, or if it feels heavy, thick, and oily." If this sounds familiar, just condition the tips for a week or two to let your scalp balance out.

5. Picking The Wrong Shampoo

The kind of shampoo you use can really impact the oil levels of your hair. If you're struggling with grease, test out a few different brands specifically targeted at treating oily hair. If nothing is working, definitely reach out to a dermatologist!

6. Not Getting Enough B Vitamins

You are what you eat, and your intake of B vitamins directly correlates with your level of sebum (oil) production. HealWithFood shared, "a sufficient intake of the B vitamins, particularly of vitamin B2 (riboflavin) and vitamin B6 (pyridoxine), can help combat greasy hair by regulating sebum production." My personal favorite way to get B vitamins is eating beans!

7. Hormonal Fluctuations

Birth control (and stress) can trigger hormonal fluctuations that lead to excess sebum production and greasy roots. If you recently started a new pill and are suddenly struggling with consistently greasy hair, check in with your doc.

8. Over-Shampooing

It seems like the solution to greasy hair would be washing it more frequently, but over-washing your hair can cause your strands to dramatically counterbalance and create even more oil. Try to stick to once a day.

9. Untreated Seborrheic Dermatitis

Seborrheic dermatitis can cause your scalp to become greasy and itchy, and will also likely produce flaky scales. Dandruff shampoos can help cure seborrheic dermatitis, but this is another matter where you should feel completely comfortable reaching out to your doctor if you think you have it.
