The Science Behind Hair Care: Avoiding Damage from Common Practices

by James La on March 15, 2024

Hair is not only a significant aspect of our appearance but also reflects our overall health and well-being. However, despite our best intentions, some of our everyday hair care practices may inadvertently lead to damage, resulting in brittle, frizzy, or even hair loss. In this blog post, we will delve into the science behind common hair care practices such as brushing wet hair, using harsh accessories, and washing with hot water, and how they can cause damage.

Brushing Wet Hair

Many of us have been guilty of vigorously brushing our hair immediately after stepping out of the shower. However, did you know that this seemingly harmless practice can actually lead to significant damage? When hair is wet, it is at its most fragile state as the water weakens the bonds within the hair shaft. Additionally, wet hair is more prone to stretching and breaking, especially if it's brushed with force.

The Solution: Instead of using a brush, opt for a wide-tooth comb or a specialized detangling brush designed for use on wet hair. Start detangling from the ends and work your way up gently, minimizing the risk of breakage.

Using Harsh Hair Accessories

From tight hair ties to metal clips, some hair accessories can be harsh on your locks, leading to damage over time. Tight elastics, in particular, can cause tension on the hair shaft, leading to breakage and even traction alopecia, a condition characterized by hair loss due to constant pulling.

The Solution: Opt for hair accessories made from softer materials like silk scrunchies or fabric-covered elastics. These options are gentler on your hair and less likely to cause breakage or damage.

Washing with Hot Water

While a hot shower can be soothing, it may not be the best choice for your hair. Hot water can strip the scalp and hair of its natural oils, leading to dryness and potential damage. Additionally, hot water can cause the hair cuticle to swell, making it more susceptible to breakage and frizz.

The Solution: Wash your hair with lukewarm or cool water instead of hot water. This helps to preserve the natural oils in your scalp and keep the hair cuticle smooth, reducing the risk of damage.



In conclusion, while hair care practices may seem innocuous, they can have a significant impact on the health and appearance of your hair. By understanding the science behind these practices and making small adjustments to your routine, you can minimize damage and promote healthier, more vibrant locks. So, the next time you reach for that brush or step into the shower, remember to consider the long-term effects on your hair and make choices that prioritize its health and well-being.
