What Are the Key Characteristics of Chemically Treated Hair?

Chemically treated hair has distinct characteristics that result from various chemical processes. These characteristics can affect hair texture, health, and how it interacts with products.

1. Increased porosity
2. Altered texture
3. Reduced elasticity
4. Dryness and brittleness
5. Color retention (for dyed hair)
6. Fragility and breakage

Chemically treated hair often shares some common characteristics while also exhibiting unique attributes based on the specific treatments applied.

1. Increased Porosity:
   Increased porosity in chemically treated hair occurs when the outer layer of the hair cuticle is raised or damaged due to chemical processes. This leaves the hair more susceptible to moisture absorption, which can lead to frizz and changes in texture. A 2020 study by Eunyoung Kim in the Journal of Cosmetic Science found that chemically treated hair often absorbs moisture rapidly but struggles to retain it, impacting overall hair health.

2. Altered Texture:
   Altered texture is a significant characteristic following chemical treatments, such as relaxers or perms. These processes change the natural curl pattern or straightness of hair. Hair becomes smoother and straighter with relaxers, while perms create curls or waves. The American Academy of Dermatology states that individuals may need to adjust their hair care routines based on these texture changes.

3. Reduced Elasticity:
   Reduced elasticity refers to the hair’s decreased ability to stretch and return to its original shape without breaking. This can occur due to the destruction of protein structures in the hair, a common side effect of chemical treatments. According to research by Yuki Yamamoto in 2019, chemically treated hair exhibits a 30% reduction in elasticity, making it more prone to damage.

4. Dryness and Brittleness:
   Dryness and brittleness are prevalent in chemically treated hair, as the chemicals strip natural oils. This can lead to a lack of moisture, making hair feel rough and fragile. The American Hair Loss Association notes that regular conditioning and moisturizing treatments are essential for maintaining healthy moisture levels in chemically treated hair.

5. Color Retention:
   Color retention is vital for dyed chemically treated hair. The chemical processes used in dyeing can lighten the hair, making it more porous. This results in better color uptake but can also lead to rapid fading. A 2021 study by Mei Ling Zhang reported that properly maintaining color-treated hair can involve using sulfate-free shampoos and UV protection to help preserve vibrancy.

6. Fragility and Breakage:
   Fragility and breakage in chemically treated hair occur because of the structural changes that weaken the hair shaft. This makes hair more susceptible to daily wear and tear, ultimately leading to split ends. Data from the International Journal of Trichology highlights that individuals with chemically treated hair may experience up to 50% more breakage compared to untreated hair, emphasizing the need for gentle handling and specialized hair care products.
