From the Guidelines
Rapid alterations in hair texture within a short time frame of less than sixty minutes are typically caused by external factors such as humidity, heat styling tools, hair products, or getting hair wet, rather than biological processes. When considering the potential causes of rapid changes in hair texture, it's essential to differentiate between external and internal factors. External factors can cause immediate changes, whereas internal or biological processes, such as those discussed in the context of chemotherapy-induced alopecia (CIA) or endocrine therapy-induced alopecia (EIA) 1, occur over a more extended period, typically weeks or months. The study on prevention and management of dermatological toxicities related to anticancer agents 1 provides insight into the effects of chemotherapy on hair, including changes in color and texture, but these changes are not instantaneous and are part of a broader process that unfolds over time. Key points to consider in the context of rapid hair texture changes include:
- Humidity and its effect on hair frizz or curl
- The use of heat styling tools and their temporary alteration of hair structure
- The application of hair products that can change the appearance of hair
- The temporary effects of getting hair wet on its texture These factors can all contribute to rapid, though typically temporary, changes in hair texture, and understanding their role is crucial for managing and predicting such changes in everyday life.

From the Research
Rapid Alterations in Hair Texture
Rapid alterations in hair texture within a short time frame of less than sixty minutes can be caused by various factors, including:
- Exogenous exposures such as hair cosmetics, heat, water, and chemical hair straighteners 3, 4
- Chemical hair straightening treatments, which can lead to significant changes in hair texture, including a decrease in hair curl and an increase in hair smoothness and shine 4
- Other factors such as hormonal and nutritional conditions, systemic intoxications, and genetic traits, although these may not cause rapid alterations in hair texture within a sixty-minute time frame 3, 5
Hair Texture Changes Due to Chemical Treatments
Chemical hair straightening treatments can cause rapid alterations in hair texture by:
- Repairing the broken cuticle of the hair fiber 4
- Penetrating the cortex of the hair fiber and improving its mechanical properties 4
- Promoting a surface coating that prevents or decreases water diffusion through the hair fibers 4
Limitations of Current Research
While there is evidence to suggest that chemical hair straightening treatments can cause rapid alterations in hair texture, there is limited research on the specific causes of rapid alterations in hair texture within a sixty-minute time frame. Further studies are needed to fully understand the mechanisms by which individual nutrients and exogenous exposures contribute to hair growth and maintenance 3, 5
