Is oiling hair before shampooing important?

Hair care routines have evolved significantly over the years, incorporating various techniques and products. Among the many age-old practices that have stood the test of time, oiling hair before shampooing remains a cornerstone, especially in Indian households. But is this ritual really essential, or is it just an age-old myth? Let’s explore the benefits, potential drawbacks, and science behind oiling hair before shampooing to understand its true importance.
Benefits of oiling hair before shampooing
1.Nourishes the scalp and hair
Oiling your hair before shampooing provides deep nourishment to both the scalp and hair. Natural oils such as coconut oil, almond oil, and olive oil are rich in essential fatty acids, vitamins, and minerals. These nutrients penetrate the hair shaft and scalp, providing moisture and essential nutrients that strengthen the hair from within.

2. Reduces protein loss
Hair is primarily composed of a protein called keratin. Regular shampooing, exposure to environmental pollutants, and heat styling can cause significant protein loss from the hair. Studies have shown that applying oil, especially coconut oil, before shampooing can reduce protein loss by forming a protective layer around the hair shaft.
3. Prevents dryness and frizz
Shampoos, particularly those containing harsh chemicals, can strip the hair of its natural oils, leading to dryness and frizz. Pre-shampoo oiling helps create a barrier that prevents excessive loss of moisture during washing, keeping the hair soft, manageable, and frizz-free.
4. Improves blood circulation
Massaging oil into the scalp stimulates blood circulation. Improved blood flow to the hair follicles enhances the delivery of oxygen and nutrients, promoting healthier hair growth and reducing hair fall.
5. Eases detangling
Oiling the hair before washing makes it easier to detangle. The oil adds slip to the hair strands, reducing breakage and damage caused by combing and brushing.

The science behind pre-shampoo oiling
The practice of oiling hair before shampooing is not just a tradition but is supported by scientific evidence. Oils like coconut oil have a unique ability to penetrate the hair shaft due to their low molecular weight and straight chain structure. This penetration helps in reducing the swelling of hair fibers when they absorb water during washing, thus minimizing hygral fatigue (repeated swelling and drying that leads to hair damage).
Moreover, oils contain fatty acids like lauric acid, which have antibacterial and antifungal properties. This helps in maintaining scalp health by preventing infections and dandruff.
How to oil your hair before shampooing
1. Choose the right oil
Select an oil that suits your hair type and needs. Coconut oil is excellent for deep conditioning, almond oil is great for nourishing the scalp, and olive oil is perfect for adding shine and softness.
2. Warm the oil
Warm the oil slightly before application. Warm oil penetrates the hair shaft more effectively and feels soothing on the scalp.
3. Massage gently
Apply the oil to your scalp and hair, massaging gently with your fingertips in circular motions. This not only helps in better absorption but also stimulates blood circulation.
4. Leave it on
Leave the oil on your hair for at least 30 minutes. For deeper conditioning, you can leave it on overnight and wash it off in the morning.
5. Shampoo thoroughly
Use a mild shampoo to wash off the oil. Ensure you rinse your hair thoroughly to remove any residual oil.

Potential drawbacks of pre-shampoo oiling
While oiling has numerous benefits, there are potential drawbacks if not done correctly:
1. Residue buildup
If the oil is not washed out properly, it can lead to residue buildup on the scalp and hair, causing greasiness and attracting dirt.
2. Over-oiling
Using too much oil can weigh down the hair, making it look limp and greasy. It’s important to use an appropriate amount based on your hair length and type.
3. Allergic reactions
Some people may have allergic reactions to certain oils. It’s advisable to do a patch test before applying any new oil to your scalp and hair.
