For generations, hair oiling has been regarded as a powerful ritual for nourishing the hair and scalp. But beyond tradition, modern cosmetic science now supports many of the benefits people have observed for centuries. Research on hair fiber biology, lipid structure, and scalp physiology shows that the right oils can protect, restore, and strengthen the hair in ways that synthetic treatments often can’t.
At Hathor by Ghalia, our formulations are inspired by this science combining ancient ritual with modern biology. Here’s what happens beneath the surface when you oil your hair.
Strengthens the Hair Shaft Through Lipid Reinforcement
Human hair is composed primarily of keratin proteins surrounded by a lipid layer called the cell membrane complex (CMC). This lipid structure is essential for:
Â
•Maintaining elasticity

•Preventing breakage

•Keeping moisture inside the hair fiber


Many oils particularly coconut oil contain medium-chain triglycerides that penetrate the hair shaft due to their low molecular weight. Studies show that coconut oil reduces protein loss during washing and UV exposure.
Result: stronger, less break-prone hair.
Reduces Hygral Fatigue (One of the Hidden Causes of Damage).
When hair gets wet, it swells. When it dries, it contracts. Repeated swelling and contraction causes structural stress known as hygral fatigue, which leads to:
Â
•Weakening of the cuticle

•Increased frizz

•Split ends


Applying oil before washing creates a hydrophobic (water-resistant) layer that prevents excessive water uptake, thereby reducing this fatigue.
Outcome: better resistance to everyday wash damage.
Supports a Healthy Scalp Microbiome
Your scalp hosts a living ecosystem of microorganisms the scalp microbiome that protects against irritation, inflammation, and dandruff. Disruption of this microbiome can lead to dryness or sensitivity.
Â
Many plant oils contain antioxidants, fatty acids, and antimicrobial compounds (such as linoleic acid or phenolic compounds) that help:
Â
•Balance microbial activity

•Reduce irritation

•Strengthen the scalp barrier

Oils like jojoba and almond also mimic the skin’s natural sebum, helping regulate scalp moisture.
Â
Enhances Cuticle Smoothness and Optical Shine
The outer layer of hair the cuticle acts like overlapping shingles. When smooth and flat, they reflect light, giving hair a glossy sheen. When damaged, they scatter light and cause dullness.
Oils help by:
Â
•Filling microscopic gaps

•Smoothing rough cuticles

•Improving uniformity of the hair surface


This creates natural shine without silicones, making the hair look healthier while retaining breathability.
Â
Reduces Mechanical Damage From Styling
Brushing, heat styling, towel-drying, and friction from pillows all create micro-tears in hair fibers. The lubricating effect of oils reduces friction between strands, lowering mechanical stress.
Â
With consistent oiling:
Â
•Hair becomes easier to detangle

•Breakage during styling decreases

•Strands maintain flexibility and tensile strength


This benefit is particularly evident in curly and coily hair types, which naturally experience more friction.
Â
Helps Maintain Moisture Balance Through Occlusion
Oils act as occlusive agents, meaning they create a lightweight barrier that slows moisture loss. While oils don’t add water to the hair, they prevent dehydration by keeping existing moisture locked in.
Â
This is essential for:
Â
•Chemically treated hair

•Heat-damaged hair

•Hair exposed to dry climates


By maintaining moisture balance, hair retains elasticity and resists snapping.
Â
Boosts Circulation and Follicle Environment Through Massage
Oiling combined with scalp massage has measurable physiological effects. Massage increases cutaneous blood flow, delivering:
Â
•More oxygen
•More nutrients
•Essential growth factors

This helps support a healthy follicle environment the foundation for natural growth cycles.
Essential oils like rosemary and peppermint (if included in your formula) have been studied for their ability to enhance circulation and stimulate follicles further.
Final Thoughts:
Where Ancient Ritual Meets Modern Biology
Hair oiling is far more than a traditional beauty practice it’s a scientifically supported method for improving scalp health, fiber strength, and overall hair resilience. At Hathor by Ghalia, we design each formula with these biological principles in mind, so every application becomes a therapeutic, scientifically grounded ritual for your hair.
