Struggling with greasy hair that feels heavy and looks unwashed? If you've been wondering "why is my hair so oily lately?", you've come to the right place. This comprehensive guide will shed light on the causes of oily hair and provide practical solutions for managing it.

Why is my hair so oily lately?

Your hair could be oily lately due to an increase in sebum production, the natural oil secreted by your scalp. This increase can be attributed to various factors such as hormonal fluctuations, stress, unhealthy eating habits, certain medications, improper hair care, and even weather changes. While sebum is essential for hair health, too much of it can make your hair look slick and greasy (source).

Understanding The Causes

Understanding why your hair is oily requires a deeper look into the factors influencing sebum production. Factors like hormonal fluctuations, particularly during puberty or pregnancy, can increase sebum production, leading to oily hair. Stress can also boost the production of oil on your scalp, and unhealthy eating habits may exacerbate the issue (source).

Certain medications and a lack of proper hair care could also be to blame. Over-washing your hair or using unsuitable hair products can strip the scalp of its natural oils, causing it to produce more oil in response. Weather changes, particularly increased humidity, can also cause an uptick in oil production (source).

Tackling Oily Hair

Dealing with oily hair can be challenging, but several strategies can help. Special shampoos designed for oily hair can be beneficial as they cleanse your hair of excess oil without overly stripping the scalp. Using a shampoo with tea tree oil, known for its detoxifying properties, can also help refresh and volumize your hair (source).

Adopting healthier eating habits, managing stress, and adjusting your hair care routine could also help reduce oiliness. If you suspect medication or an underlying health issue is causing your oily hair, consulting with a healthcare professional is recommended.


Dealing with oily hair can be frustrating, but understanding the possible causes and knowing how to manage them can make a significant difference. While it may take some time to see improvements, consistent application of these strategies can help you manage and reduce oily hair. Remember that everyone's hair is different, and it may take some trial and error to find the best solution for you.
