How To Fix Oily Straightened Hair: A Comprehensive Guide

Having straight, sleek hair is the dream for many. But often, straightening leads to excess oil production and greasy locks. If you’ve ever wondered how to control oil on straightened hair, you’re not alone.

The good news is that with the right hair care regimen, it is possible to have straight hair without the grease. Read on as we explore the causes of oily straightened hair and provide solutions to cut down on oil for good.

What Causes Oily Hair After Straightening?

Many people experience oily hair after straightening, and there are several reasons why this may occur. Understanding the causes can help you take the necessary steps to fix the issue and maintain healthy, oil-free hair.

Heat styling leads to overproduction of sebum

When you straighten your hair using heat styling tools such as flat irons, curlers, or blow dryers, the heat can stimulate the sebaceous glands in your scalp to produce more sebum. Sebum is the natural oil produced by your scalp to moisturize and protect your hair.

However, excessive heat can cause these glands to overproduce sebum, resulting in oily hair.

To prevent this, it’s important to use heat styling tools at the appropriate temperature and avoid excessive heat exposure. Additionally, using heat protectant products before styling can help minimize the damage and reduce the chances of oily hair.

Hair damage from flat ironing and chemicals

Another common cause of oily hair after straightening is hair damage. Flat ironing and chemical treatments, such as relaxers or keratin treatments, can strip your hair of its natural oils, causing your scalp to compensate by producing more sebum.

This excess sebum can make your hair look greasy and oily.

To prevent hair damage, it’s important to use flat irons with adjustable temperature settings, and avoid using them on high heat settings. Additionally, opting for hair treatments that are less harsh on your hair, such as protein-based treatments, can help minimize damage and reduce oily hair.

Using the wrong hair products

The hair products you use can also contribute to oily hair after straightening. Using heavy or greasy styling products, such as serums, oils, or leave-in conditioners, can weigh down your hair and make it appear greasy.

Additionally, using the wrong shampoo or conditioner for your hair type can also lead to oily hair.

To avoid this, choose lightweight, oil-free hair products that are specifically designed for straightened or heat-styled hair. Look for products labeled as “oil-free,” “lightweight,” or “volumizing.” These products can help control oil production and keep your hair looking fresh and oil-free.

Remember, everyone’s hair is unique, and what works for one person may not work for another. It may take some trial and error to find the right combination of products and techniques to keep your straightened hair oil-free. Don’t be afraid to experiment and seek professional advice if needed.

Tips to Control Oil on Straightened Hair

Wash hair less frequently

One of the best ways to control oil on straightened hair is to wash it less frequently. Washing your hair every day can strip away the natural oils, causing your scalp to produce more oil to compensate. Instead, try washing your hair every two to three days.

This allows your scalp to regulate its natural oil production, resulting in less oily hair.

Use a clarifying shampoo once a week

A clarifying shampoo can be a game-changer when it comes to controlling oil on straightened hair. Clarifying shampoos are designed to remove product buildup and excess oil from the hair and scalp. Use a clarifying shampoo once a week to deeply cleanse your hair, helping to keep it fresh and oil-free.

Apply dry shampoo between washes

Dry shampoo is a fantastic tool for managing oily hair between washes. It works by absorbing excess oil from the scalp, giving your hair a refreshed and clean appearance. Simply spray dry shampoo onto your roots, let it sit for a few minutes, and then brush it out.

This will instantly revive your hair and reduce oiliness.

Focus on conditioning the ends

When conditioning your hair, focus mainly on the ends rather than the roots. The ends of your hair tend to be drier and more prone to damage, while the roots produce more oil. By applying conditioner primarily to the ends, you can hydrate and nourish them without adding extra oil to the scalp.

Avoid oil-based products

If you’re dealing with oily straightened hair, it’s important to avoid using oil-based hair products. These products can weigh down the hair and make it appear greasier. Instead, opt for lightweight and water-based products that won’t add unnecessary oil to your hair.

Reduce heat styling

Excessive heat styling can contribute to oiliness in straightened hair. The heat from styling tools can stimulate the scalp’s oil production, making your hair greasier. Try to minimize the use of heat styling tools and opt for air-drying or using heat-free styling methods when possible.

By following these tips, you can effectively control oil on straightened hair and enjoy a fresh and vibrant look. Remember, finding the right balance of washing and conditioning, using the right products, and minimizing heat styling can make a significant difference in managing oiliness.

How to Wash Straightened Hair

Use a sulfate-free shampoo

One of the most important steps in maintaining and fixing oily straightened hair is to use a sulfate-free shampoo. Sulfates are harsh cleansing agents that can strip the hair of its natural oils, leading to dryness and increased oil production.

By opting for a sulfate-free shampoo, you can effectively cleanse your hair without further drying it out. Look for shampoos that are specifically formulated for oily hair types and contain ingredients like tea tree oil or witch hazel, which have natural astringent properties.

These can help to balance the scalp’s oil production and prevent excessive oiliness.

Rinse with cool water

When washing straightened hair, it’s important to rinse with cool water instead of hot water. Hot water can strip away the natural oils from the hair, leaving it dry and prone to oiliness. Cool water, on the other hand, helps to close the hair cuticles, sealing in moisture and preventing excessive oil production.

Additionally, rinsing with cool water can give your hair a smoother and shinier appearance, which is always a plus!

Gently pat dry with a towel

After washing your straightened hair, avoid rubbing it vigorously with a towel as this can cause frizz and damage. Instead, gently pat your hair dry with a soft towel to absorb excess water. It’s also a good idea to avoid using a terrycloth towel, as the rough texture can rough up the hair cuticles and contribute to frizz.

Opt for a microfiber towel or an old t-shirt, which are much gentler on the hair.

Apply a leave-in conditioner

Once your hair is towel-dried, it’s important to apply a leave-in conditioner to help nourish and hydrate your hair. Look for a lightweight leave-in conditioner that is specifically formulated for oily hair, as heavy products can weigh down your hair and make it appear greasy.

Apply the leave-in conditioner from mid-length to the ends of your hair, avoiding the roots to prevent further oiliness. This step will help to replenish moisture and protect your hair from environmental damage.
