The cuticle is the outer layer of the hair shaft and plays a crucial role in protecting the inner part of the hair, the cortex, from damage. It consists of several layers of flat, overlapping cells arranged like shingles on a roof. This configuration helps protect the hair from the penetration of harmful substances and retains moisture, which is essential for maintaining its strength and elasticity.
Functions of the cuticle
- Protection : The main function of the cuticle is to protect the inner structure of the hair, the cortex, from external influences such as UV rays, heat, chemical treatments and mechanical damage.
- Moisture retention : The cuticle helps to retain moisture in the hair, which is essential for preventing dryness and brittleness.
- Light reflection : A healthy, intact cuticle layer reflects light, giving the hair its shine.
Cuticle damage
The cuticle can be damaged by a variety of factors, including:
- Chemical treatments : Dyeing, bleaching and perming can weaken the cuticle and lead to porosity and breakage.
- Heat : Regular use of heat styling tools such as flat irons, curling irons and hair dryers at high temperatures can damage the cuticle.
- Mechanical stress : Rough brushing, combing and styling can break down the cuticle cells.
- Environmental factors : Strong sunlight and salt water can also contribute to cuticle erosion.
Cuticle care
To maintain the health of the cuticle and thus the entire hair, the following measures are recommended:
- Gentle styling : Use a wide-toothed comb and avoid brushing your hair while it is wet to minimize mechanical damage.
- Heat protection : Use heat protection products before using styling tools and try to limit the application of heat.
- Moisturizing care : Use moisturizing hair care products to retain moisture in the hair.
- Limit chemical treatments : Try to reduce the frequency of chemical treatments and have them carried out by professionals to minimize damage.
- Protection from environmental influences : Wear a hat or use hair products with UV protection to protect your hair from the sun.
Maintaining a healthy cuticle is crucial for strong, shiny, and healthy hair. By preventing damage and providing the right care, the integrity of the cuticle can be preserved and the appearance of the hair improved.
