Managing oily hair can be tricky, especially when looking for a serum that provides moisture and shine without adding extra greasiness. 

The right hair serum for oily hair can help balance oil production, nourish your scalp, and control frizz while maintaining a lightweight feel. 

With ingredients like vitamin C, salicylic acid, and tea tree oil, these serums work to clarify, hydrate, and keep your hair looking fresh throughout the day.

In this guide, we’ve rounded up the 7 best and proven hair serums for oily hair. These products help tame excess shine, promote a healthier scalp, and provide controlled volume, leaving your hair feeling refreshed, soft, and non-greasy.

What causes oily hair?

Oily hair is primarily caused by the overproduction of sebum, a natural oil produced by sebaceous glands on your scalp. This oil is crucial for maintaining healthy hair as it conditions and protects your hair strands. However, when produced excessively, it can result in an oily scalp and greasy hair.

The overproduction of sebum can be attributed to several factors. Hormonal changes, particularly during puberty, pregnancy, or menstrual cycles, can often lead to increased oil production. 

Additionally, stress, poor diet, certain medications, and improper hair care habits, such as over-washing or under-washing your hair, can also stimulate excess sebum production.

Furthermore, your hair type and texture can play a significant role. 

For instance, individuals with fine or thin hair often struggle with oiliness because they have more hair follicles (and hence more oil glands) per square inch of scalp. 

On the other hand, curly or coarse hair might seem less oily as the oil takes more time to travel down the hair shaft. 

Understanding the cause behind your oily hair can help you choose the right hair care products and develop effective routines to manage it better.

Is hair serum good for greasy hair?

Yes, hair serum can be beneficial for greasy hair, but it's crucial to choose the right type of serum specifically designed for oily hair. These serums work to balance the oil production in your scalp, hydrate your hair adequately, and prevent it from looking flat and lifeless due to excess oil.

Hair serums are generally formulated with active ingredients that serve various purposes, and in the case of serums for oily hair, these ingredients aim to regulate sebum production without stripping away the natural oils your hair needs to stay healthy. 

Furthermore, such serums can provide a protective layer to shield your hair from environmental aggressors, heat damage, and other harmful elements, reducing the need for your scalp to produce excess oil as a protective response.

The Bio-Pilixin Activation Serum represents a formidable fusion of science and nature's bounty, offering an innovative solution in the realm of hair serums. 

Its formulation is particularly noteworthy for those with oily hair, as it aims to help with common issues like the appearance of hair loss and thinning, and provides an environment that may contribute to a balanced look and shine.

The inclusion of Vanillyl Butyl Ether, a gentle warming agent, boosts blood circulation in the scalp, which facilitates the absorption and effectiveness of other active ingredients in the serum.

How to get rid of oily hair?

To get rid of oily hair, follow these steps:

  1. Choose the right shampoo and conditioner: Use a shampoo formulated for oily hair to help regulate sebum production. When conditioning, focus on the ends of your hair to avoid excess oil on your scalp.

  2. Limit hair washing: Avoid washing your hair every day, as it can stimulate your scalp to produce more oil. Wash your hair every 2-3 days to maintain a balanced oil level.

  3. Use hair serums for oily hair: Select a lightweight, non-greasy hair serum and apply it to the mid-lengths and ends, not the scalp, to manage oil without weighing your hair down.

  4. Maintain a balanced diet: Avoid greasy foods, as they can increase oil production. Incorporate fruits, vegetables, and lean proteins into your diet to help regulate oil levels.

  5. Avoid touching your hair: Touching your hair transfers oils from your fingers, making it appear oilier. Try to keep your hands off your hair as much as possible.

And there you have it - our top 7 hair serums, curated and meticulously chosen to help you combat oily hair and reinvent your hair care regimen.
