If you have curly hair, you know it behaves differently from straight or wavy hair. Curly hair tends to dry faster, become frizzy, tangle easily, and often needs extra care to stay healthy. One of the most effective ways to nourish curls and keep them soft, strong, and defined is through proper hair oiling.
But which oil should you use? How much? How often? And what is the correct method?
Curly hair thrives on moisture but also needs nourishment that penetrates deep into the hair strands. Many curlies either over oil their hair, under oil it, or use oils that do not match their curl pattern, hair porosity, or hair density.
This ultimate guide will help you understand everything about oiling curly hair from the benefits and types of oils to the best application techniques so your curls look healthy, hydrated, and absolutely gorgeous.
Why Curly Hair Needs Oiling
Curly hair is naturally prone to dryness and brittleness. Because curls twist and bend, natural oils (or natural sebum) produced by the scalp struggle to travel down the hair shaft. This leaves the hair ends dry, frizzy, and prone to breakage.
Oiling helps to:
-
Lock in moisture and retain moisture within the hair strands
-
Strengthen hair follicles and reduce hair breakage
-
Enhance natural shine and smoothness of curls
-
Improve curl elasticity and definition
-
Support overall hair health and stimulate hair growth
-
Soothe and nourish the scalp, improving scalp health
Oiling curly hair is not just a beauty ritual, it’s a scientifically supported method to improve long-term hair and scalp health.
Understanding Hair Porosity and Hair Density
What is Hair Porosity?
Hair porosity refers to how well your hair absorbs and retains moisture. It depends on the condition of your hair cuticles:
-
Low porosity hair has tightly closed cuticles that repel moisture, making it harder for oils and conditioners to penetrate.
-
High porosity hair has open or damaged cuticles that absorb moisture quickly but also lose it fast, leading to dryness and brittleness.
-
Medium porosity hair strikes a balance, absorbing and retaining moisture well.
Knowing your hair’s porosity helps you select the right hair oils and care routine.
What is Hair Density?
Hair density is the number of hair strands per square inch on your scalp. It affects how much oil your hair can handle without weighing it down. Fine hair with low density benefits from lightweight moisturizing oils, while thick, coarse hair with high density can handle heavier oils.
Best Oils for Curly Hair
Not all oils are created equal. Some penetrate deeply into the hair shaft (moisturizing oils), while others form a protective barrier on the hair surface (sealing oils). Choosing the right hair oil depends on your curl pattern, porosity, and hair density.
Moisturizing Oils
These oils have smaller molecules that penetrate the hair shaft to hydrate and nourish from within.
-
Coconut Oil: Coconut oil is one of the most powerful oils for curly hair because of its unique ability to penetrate deep into the hair shaft rather than just coating the surface. Rich in fatty acids, particularly lauric acid, it helps reduce protein loss, making curls stronger and less prone to breakage. Its intense moisturizing properties make it ideal for dry, damaged, or high porosity curls, which often struggle to retain hydration. Coconut oil also smooths the cuticle, resulting in softer, shinier, and more manageable curls.
-
Argan Oil: Often called “liquid gold,” argan oil is prized for its lightweight, non-greasy texture, making it perfect for all curl types, including fine and medium hair. It is packed with vitamin E, antioxidants, and essential fatty acids, which help restore elasticity, reduce frizz, and protect hair from environmental damage. Argan oil adds instant shine and softness without weighing curls down, making it a go-to for enhancing definition and achieving a polished look.
-
Jojoba Oil: Jojoba oil closely mimics the hair’s natural sebum, allowing it to hydrate and balance the scalp without clogging pores. It is excellent for soothing dry, itchy, or flaky scalps, while providing lightweight moisture for fine curls that get weighed down easily by heavier oils. Because it sits on the hair surface and provides a protective layer, jojoba oil helps reduce frizz and adds a natural, healthy sheen to curls.
-
Almond Oil (Sweet Almond Oil): Sweet almond oil is a lightweight, nutrient rich oil full of omega 3 fatty acids, magnesium, and vitamins A and E. It absorbs quickly into the hair, making curls feel silky, smooth, and nourished. Almond oil softens rough strands, enhances natural shine, and helps reduce split ends. It is an excellent choice for curls that need moisture without heaviness, especially for regular maintenance and shine boosting.
-
Avocado Oil: Avocado oil is a deeply nourishing oil loaded with vitamins A, D, E, antioxidants, and monounsaturated fatty acids. Its rich composition allows it to penetrate the hair shaft, strengthening curls from within while improving elasticity and manageability. It is especially beneficial for dry, brittle, or over processed curls, as it replenishes lost moisture, supports repair, and leaves the hair smooth, strong, and more resistant to breakage.
Sealing Oils
-
Sealing oils are designed to create a protective barrier on the hair, locking in moisture and shielding curls from environmental damage such as heat, pollution, and humidity. They are essential for maintaining hydration, reducing frizz, and ensuring curls remain soft, shiny, and manageable throughout the day.
-
Castor Oil: Thick and dense, castor oil is a powerhouse for locking in moisture and preventing dryness. It strengthens brittle hair, reduces breakage, and supports hair growth by nourishing the scalp and stimulating follicles. Ideal for coarse or damaged curls that need intense hydration and reinforcement.
-
Olive Oil: A heavier, nutrient rich oil that penetrates the hair shaft to deeply nourish and soften curls. Olive oil is perfect for thick, coarse, or high porosity hair that requires extra moisture, while also enhancing shine and improving overall manageability.
-
Grapeseed Oil: Lightweight yet effective, grapeseed oil seals in moisture without weighing curls down. It smooths the hair cuticle, reduces frizz, and adds a natural shine, making it suitable for fine to medium curly hair.
-
Rosemary Oil: Known for its scalp stimulating properties, rosemary oil promotes healthy hair growth by improving circulation to the follicles. It also strengthens strands, reduces hair thinning, and enhances scalp health, making it an excellent addition to any curly hair care routine.
How to Apply Hair Oil Correctly
Proper application is key to maximizing benefits and avoiding greasy buildup.
Step 1: Choose the Right Hair Oil
Match the oil to your hair type, porosity, and hair density. For example, use lighter moisturizing oils for fine or low porosity hair and heavier sealing oils for thick or high porosity hair.
Step 2: Warm the Oil
Warm oil absorbs better and increases blood circulation. Place your chosen oil in a bowl of hot water for a few minutes or rub a few drops between your palms.
Step 3: Section Your Hair
Divide your hair into manageable sections to ensure you can oil evenly and reach all areas of your scalp and hair strands.
Step 4: Apply Hair Oil to the Scalp and Hair
Using your fingertips, gently massage the oil into your scalp using circular motions to stimulate scalp health and hair follicles. Then, apply oil evenly through the lengths and ends of your hair, focusing on the driest areas.
Step 5: Use Scalp Massages
Massaging for 5-10 minutes helps improve blood flow, stimulates hair growth, and nourishes the scalp.
Step 6: Leave It On
For a pre-shampoo treatment or hot oil treatment, leave the oil on for at least 30 minutes or overnight for deep moisture. Use a shower cap or warm towel to trap heat and enhance absorption.
Step 7: Cleanse Gently
Use a gentle, sulfate-free shampoo to remove oil without stripping moisture. Avoid over shampooing to maintain hair’s natural oils.
Tips for Application
-
Apply oil on damp hair or after you gently towel dry your hair (avoid soaking wet hair). This helps lock in moisture.
-
Use only a few drops to avoid weighing hair down or causing buildup.
-
Avoid applying too much oil to roots if you have an oily scalp or fine hair.
-
Combine moisturizing and sealing oils for best results.
Hot Oil Treatment for Curly Hair
Hot oil treatments are an intensive way to hydrate and restore dry and frizzy hair. Warm oil penetrates the hair shaft more effectively, sealing the cuticle and improving hair elasticity and shine.
How to do a hot oil treatment:
-
Warm your chosen oil(s) (e.g., coconut or castor oil) gently.
-
Apply evenly to scalp and hair strands, massaging well.
-
Cover hair with a shower cap and wrap a warm towel around your head.
-
Leave on for 30-60 minutes or overnight for deep conditioning.
-
Rinse thoroughly and shampoo gently.
Leave-In Conditioner and Hair Oils
Some oils can be used as a leave-in conditioner to maintain hydration, reduce frizz, and add instant shine throughout the day. Use a small amount on damp hair and avoid over application to prevent greasy hair.
Common Mistakes to Avoid
-
Applying oil to soaking wet hair, which dilutes the oil and reduces absorption.
-
Using too much oil, causing greasy, weighed-down curls.
-
Skipping scalp massages, missing out on stimulating hair follicles and scalp health.
-
Using mineral oils or synthetic products that clog pores and damage hair.
-
Not matching the right hair oil to your hair type or porosity.
