Summary
Female alopecia is rising in young women. This study links oily scalps to specific lipid and microbial changes, offering new insights into hair loss causes in this demographic.
Area of Science:
- Dermatology
- Microbiology
- Biochemistry
Background:
- Female alopecia is an increasing concern, particularly among younger individuals.
- Limited research exists on the specific causes of alopecia in young women.
Purpose of the Study:
- To investigate the potential causes of hair loss in young Chinese females (18-35 years old) experiencing oily scalps.
- To identify correlations between scalp conditions and hair loss in the target demographic.
Main Methods:
- Utilized non-invasive techniques to measure scalp physiological parameters.
- Analyzed scalp lipid composition using Ultra-Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS).
- Examined scalp microbiota through macro-genome sequencing and conducted multidimensional combined analysis.
Main Results:
- Identified significant differences in scalp physiological indices, lipid profiles, and microbial community structures between individuals with and without hair loss.
- Screened eight specific differential lipids strongly associated with hair loss.
- Detected microorganisms with high relative abundance at both phylum and genus levels.
Conclusions:
- Abnormalities in specific scalp lipids and metabolic pathways are linked to hair loss and oily scalp conditions.
- Alterations in scalp microbiota composition are associated with hair loss in young women.
- Findings suggest a complex interplay between lipids, metabolism, and microbial environment in female alopecia.

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...
