Lipids promote hair growth
Lipids play a crucial role in promoting hair growth and maintaining hair health. They are key players in the dynamic equilibrium between cells and tissues, acting as energy sources, building blocks for cell components, and signalling molecules. The hair follicle, with its constant cycle of loss and regeneration, is one of the most dynamic tissues in the human body.
The role of lipids in hair health is multifaceted. Firstly, they serve as a protective barrier, preventing the penetration of foreign matter and the loss of internal moisture. This barrier is essential in safeguarding hair from environmental and chemical damage, reducing breakage and thinning. Secondly, lipids enhance the shine, elasticity, and tensile strength of the hair shaft, contributing to its overall manageability and healthy appearance.
The lipid composition of hair includes saturated and unsaturated fatty acids, making up 85% of the total hair lipid content. While they only constitute 2-6% of the hair's weight, these lipids are vital for maintaining hair health. Unfortunately, lipids can be lost due to various external stressors such as chemical treatments, washing with surfactants, and UV exposure. This loss of lipids can lead to a decline in hair strength and overall hair health.
To combat lipid loss, research has focused on lipid replenishment strategies. One approach involves incorporating lipids, such as fatty alcohols (FaOHs), into a gel network with anionic surfactants. This delivery system can effectively penetrate the hair, increasing internal strength. Additionally, studies have explored the effects of chemical and environmental damage on the lipid composition and properties of hair, aiming to develop strategies to defend the lipid barrier.
Furthermore, lipids have been found to promote hair growth through the HIF-1 signalling pathway. Lipid supplementation has been shown to upregulate hair growth-related genes and accelerate the elongation of hair-shaft-like structures. This discovery highlights the potential of targeting lipid metabolism as a promising treatment for hair loss.
While the specific mechanisms remain to be fully elucidated, the available evidence suggests that lipids are integral to hair health and growth. Further research and understanding of lipid metabolism and its impact on hair follicles will be crucial in developing effective treatments for hair loss.

Lipids are lost from hair through washing and chemical treatments
Lipids play a crucial role in keeping hair healthy, despite only making up 2-6% of its overall weight. They are responsible for influencing shine, feel, manageability, and strength. However, lipids are lost from hair over time through various means, including washing and chemical treatments.
Washing hair with surfactants can lead to lipid loss. Surfactants are substances that reduce the surface tension of a liquid, allowing it to spread easily. They are commonly found in shampoos and other cleansing agents. While surfactants effectively remove dirt and grease, they can also strip away natural oils and lipids from the hair. Studies have shown that the rubbing method of washing hair can lead to more significant lipid loss compared to the immersion method. This is because the rubbing method allows for the penetration of surfactants into the hair, causing lipids to accumulate in the core of surfactant micelles.
Chemical treatments, such as hair coloring, can also result in lipid loss. These treatments can alter the lipid composition and structure, leading to a degradation of lipids through oxidation. UV exposure is another factor that contributes to lipid loss in hair. The combination of UV and visible light exposure can lead to widespread changes in the hair lipidome, affecting the overall health and appearance of the hair.
The loss of lipids can have detrimental effects on hair health. Lipids act as a protective barrier, preventing the penetration of foreign matter and the loss of internal moisture. When this barrier is compromised, the hair becomes vulnerable to damage and dryness. Additionally, lipid loss can impact hair strength, making it more prone to breakage and split ends.
To mitigate lipid loss, certain strategies can be employed. Surface and internal modifications can help prevent lipid loss by creating a protective barrier on the hair surface and improving the retention of lipids within the hair shaft. Additionally, replenishing lipids can be achieved by incorporating fatty alcohols (FaOHs) into hair care products, which can enhance hair strength and overall health.

Shampoos and conditioners contain surfactants that remove lipids
Lipids are essential for hair health, influencing shine, feel, manageability, and strength. Human hair fibres are composed of lipids, which can be categorised as exogenous or endogenous. Exogenous lipids include free fatty acids (FFAs), triglycerides, cholesterol (CH), wax esters, and squalene, while endogenous lipids comprise FFAs, CH, ceramides, glycosylceramides, cholesterol sulfate, and 18-methyleicosanoic acid. Lipids play a crucial role in protecting hair from damage and maintaining its health.
Shampoos and conditioners are hair care products that contain surfactants, which are cleansing agents that remove dirt, oil, and lipids from the hair and scalp during washing. The content of surfactants in shampoos typically ranges from 10% to 20%essential for the cleansing action of shampoos. Anionic surfactants, such as sodium laureth sulphate and sodium lauryl sulphate, are the most commonly used in shampoos and are known for their lathering and detergency properties. These surfactants effectively remove lipids from the hair, impacting its lipid content and properties.
The presence of surfactants in shampoos and conditioners can have both positive and negative effects on hair health. On the one hand, surfactants help remove excess oil, dirt, and impurities from the hair and scalp, contributing to better hair and scalp hygiene. This cleansing action can also help reduce the chances of scalp inflammation, itching, and odour. Additionally, surfactants can enhance the delivery of conditioning agents, improving hair smoothness, softness, and manageability.
However, the use of surfactants in shampoos and conditioners can also lead to lipid loss in hair. Lipids form a protective barrier on the hair, shielding it from external factors and maintaining internal moisture levels. Routine washing with surfactant-containing products can damage this lipid barrier, leading to a loss of function over time. This damage can be influenced by various factors, including the surfactant structure, concentration, agitation, temperature, and exposure time. Additionally, certain chemical treatments, such as bleaching and dyeing, can deplete the outermost lipid layers, causing cuticle deterioration and increased friction.
To mitigate lipid loss and maintain hair health, it is essential to strike a balance in the use of shampoos and conditioners. While these products effectively remove lipids, excessive or aggressive use can lead to adverse effects. It is recommended to incorporate lipid-replenishing ingredients, such as fatty alcohols, into hair care routines to strengthen and protect the hair. Additionally, surface and internal modifications can be explored to prevent lipid loss and maintain the integrity of the hair's lipid barrier.

Lipid loss from hair can be prevented through surface and internal modification
Lipids play a crucial role in keeping hair healthy, influencing shine, feel, manageability, and strength. Lipids are constantly lost over time due to various factors such as washing hair with surfactants, exposure to chemical treatments, UV exposure, and environmental insults. Therefore, it is essential to understand the mechanisms of lipid loss and develop strategies to prevent it.
One study found that lipids were lost through a combination of physical damage to the cuticle layer and the chemical effects of surfactants. The study compared virgin hair to washed hair and found no significant difference in cuticle density, indicating that lipid loss was not primarily due to physical damage. Instead, it was suggested that surfactants in shampoos and other hair products contribute significantly to lipid loss.
To prevent lipid loss from hair, surface and internal modifications have been proposed as effective strategies. Surface modification involves depositing a positively charged polymer on the hair surface, which increases the polarity and wettability of the lipids, preventing their removal through a roll-up mechanism. Internal modification, on the other hand, utilizes a carbodiimide reagent to create a hydrophilic coating that retains lipids.
The effectiveness of these modifications was tested on two groups of lipids: Group A, consisting of fatty acids and cholesterol, and Group B, consisting of squalene and wax esters. Surface modification successfully reduced lipid loss in Group A but was less effective for Group B. Internal modification, however, showed remarkable results for Group B, preventing lipid loss by up to 81.3%.
In conclusion, lipid loss from hair can be significantly reduced through strategic surface and internal modifications. By understanding the mechanisms of lipid loss and implementing these modifications, it is possible to maintain healthy hair and prevent the negative consequences of lipid depletion. Further research and product development can build upon these findings to create innovative solutions for hair care.
