Summary
Hairstyling procedures like blow drying and straightening are linked to microscopic hair changes in women. Despite no differences in hair breakage or density, these styling methods significantly increase the risk of microscopic alterations.
Area of Science:
- Dermatology
- Trichology
- Cosmetic Science
Background:
- Investigating the link between hair loss, structural changes, and styling practices in women.
- Understanding the impact of cosmetic procedures on hair health.
Purpose of the Study:
- To evaluate the association between hairstyling procedures and hair structural changes (gross and microscopic) in women.
- To compare hair assessment parameters between women using styling procedures and a control group.
Main Methods:
- Cross-sectional study involving 94 women, categorized into cases (using styling procedures) and controls (no procedures in the past 6 months).
- Data collection included sociodemographics, clinical history, sun exposure, and hair product use.
- Evaluated hair pull test, hair density, hair breakage index (HBI), and performed microscopic examination.
- Logistic regression analysis was used to determine odds ratios (OR) and 95% confidence intervals (CI).
Main Results:
- No significant differences were observed in hair breakage index (HBI) or hair density between cases and controls.
- Women undergoing hairstyling procedures showed a significantly higher likelihood of microscopic hair changes (OR: 22.0, P < 0.001).
- Increased sun exposure (>3 h) was also significantly associated with microscopic hair changes (OR: 6.7, P = 0.03).
Conclusions:
- Hairstyling procedures are associated with microscopic hair changes in women, despite no observable differences in standard hair assessment parameters.
- The findings suggest a need for specific guidelines regarding hairstyling practices for Indian hair.
- Further research may explore the long-term effects and specific mechanisms linking styling procedures to microscopic hair alterations.

Accessory Structures of the Skin: Hair and Hair Follicles
4.0K
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...

Accessory Structures of the Skin: Hair Growth and Types
2.1K
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...

Multipotency and Niche of Bulge Stem Cell
4.0K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
