Using a blow dryer on low heat has several benefits compared to using high heat. Here are some reasons why people suggest using low heat:
Minimizes Heat Damage: High heat from blow dryers can cause damage to your hair, including dryness, brittleness, and split ends. By using low heat, you reduce the risk of heat-related damage, as it is less intense and doesn't excessively dehydrate your hair.
Retains Moisture: High heat can strip away moisture from your hair, leaving it dry and prone to frizz. Low heat helps to preserve the natural moisture in your hair, keeping it hydrated, smooth, and healthy-looking.
Prevents Overheating: High heat applied to your scalp can lead to discomfort, itching, and even burns. Low heat is gentler and reduces the risk of overheating your scalp, making it a more comfortable option.
Preserves Hair Color: If you have dyed or color-treated hair, using high heat can cause the color to fade more quickly. The lower heat setting helps to prevent excessive color fading and extends the longevity of your hair color.
Reduces Styling Time: While high heat can dry your hair faster, it may also make it more susceptible to damage. Low heat, though it may take longer to dry your hair completely, is a safer option and still effective for achieving your desired style.
Suitable for Fine or Delicate Hair: Fine or delicate hair types are generally more vulnerable to heat damage. Using low heat is particularly beneficial for these hair types as it minimizes the risk of causing breakage or weakening the strands.
However, it's important to note that the best heat setting for your hair can vary depending on its thickness, texture, and overall health. It's always a good idea to use heat protectant products before blow drying, regardless of the heat setting, and to avoid prolonged exposure to any high heat source to maintain the health and integrity of your hair.
