How can the risk of hair damage during blow-drying be minimized?

Applying a heat protectant before blow-drying is a well-established practice for minimizing hair damage. Heat protectants are designed to create a barrier between the hair and the heat from styling tools, preventing moisture loss and structural damage caused by high temperatures. These products often contain silicones, oils, and other ingredients that can help to coat the hair shaft, making it more resistant to heat and reducing the risk of breakage, split ends, and overall dryness.

Using cold air settings can help reduce the heat exposure, but it may not be as effective in minimizing damage as applying a protective product beforehand. Increasing drying time can lead to more exposure to heat, hence, increasing the risk of damage. Similarly, using a heavy product may weigh the hair down, potentially leading to buildup rather than protecting it from heat. Thus, applying a heat protectant is the most effective method for safeguarding the hair during the blow-drying process.
