Almost nobody of us would indeed turn down a blowout from a salon. However, it’s also true that we need the opportunity (or money) to go to our hairdressers for an expertly done style frequently. That is why the majority of us have a blow dryer at home. Having stated that, one doubt frequently crosses our minds: Is blow-drying your head bad? Continual exposure to intense heat and not using the best hair growth products is a prescription for brittle hair. However, blow-drying is good for your mane if you do it right. In fact, according to scientists, air drying can be more harmful than blow drying. (What a surprise!)
All About Hair Dryer And their Effects
Before getting started, let’s address your worries and respond to the widespread paradigm, “Is blow-drying your scalp negative?”
- Is it harmful to blow-dry your hair?
So, is it terrible to blow-dry your hair? Sometimes. According to a previous study from 2011, heat damage typically appears on the hair cuticles rather than inside the fibers. Your cuticles serve as your body’s first protection against heat from blow-drying your hair. So your hair is less likely to be damaged after blow-drying if your cuticles are healthy.
The cuticles’ ability to protect you has a natural upper limit. According to research published in the International Journal of Cosmetic Science, heat settings greater than 284 degrees Fahrenheit permanently harm the cuticles (think frizzy-looking hair and split ends). Expect destroyed hair at extreme temps of 392 degrees Fahrenheit.
That’s because hot air causes tiny bubbles to develop inside the hair shafts when applied to damp hair. Your mane becomes weaker as a result and is more prone to becoming dry and brittle. In other words, welcome to breakage, knots, and frizz.
- Is letting your hair dry a good idea spontaneously?
At this moment, air drying is superior to blow drying. The scientific community, however, strongly disagrees. Rewinding to the 2011 study on blow-drying-relaxed hair damage, one unexpected finding jumped out: blow-drying did not cause CMC damage to the hair fibers. However, air-drying did. The delta layer of the CMC and the hair shafts, in general, expand up when your hair becomes wet, which might be the cause. It can take as long as two hours for the hair to dry completely by air-drying, which is a sluggish procedure. The CMC inside the strands is continually exposed to water throughout this time and continues to swell. The scientists warned that doing so may be even more harmful than using a hair dryer.
Science-Based Advice to Reduce Blow-Drying Damage
So far, blow-drying instead of air-drying is the direction that hair-drying technology is headed. And let’s face it, many of us can only function with our preferred heat styling tool. Are there any recommendations to reduce the likelihood of blow-drying-damaged hair? Oh, yes. The secret is to make little adjustments to your haircare and style regimen that will help strengthen and preserve your hair cuticles’ condition.
- When Taking a Shower, Condition the First
The key to a blowout fit for a salon starts in the bathroom with the hair conditioner. Once it comes to enhancing the texture and appearance of your hair to make them easier to manage, it is your buddy. A conditioner seeps into the hair cuticles and might even reach the cortex layer, based on the molecular density of the chemical list. This improves luster and smoothness while reducing friction for fewer knots and frizz. After blow-drying, science advises constant conditioning to “recondition the hair.”
- Avoid blow-drying wet hair.
After getting out of the shower, avoid using the blow dryer immediately to avoid damaging your mane. Contrary to popular belief, blow-drying drenched-in-water hair is one of the surest ways to damage hair. Instead, use a microfiber towel, which is considerably more absorbent than regular terrycloth, to press out the extra water from your hair gently. Avoid forcefully massaging your hair when towel-drying it since this will cause frizz. Before moving on to the next stage, use a wide-toothed comb to untangle your hair after it feels roughly 70–80% dry.
- Make use of a silicone-based heat shield.
Okay, you’ve reached the stage of blow-drying that may be the most important: using a heat protectant. As its name indicates, a heat protectant helps limit hair damage as you blow-dry your hair. But you shouldn’t use any spray or serum that claims to protect against heat. To uniformly spread the heat throughout the hair shaft’s surface, science advises using a silicone-based heat protectant. By doing this, the likelihood of bubbling inside the fibers is decreased.
- Aware of the Heat Setting
It is no secret that the more heat your blow-dryer is set to, the more harm it will do to your cuticles and, consequently, to your mane. What is the ideal temperature, then? Following one of the previous research stated earlier, blow-drying your hair should only be done at a temperature of about 140 degrees Fahrenheit, and it’s also advisable to use the best hair growth products.
- Add a diffuser.
People with tight coils, curly hair, or loose waves should attach a dispersion to their blow dryers as soon as possible. The nozzles of most blow-dryers produce a powerful blast of hot wind that causes your curl arrangement (or straight strands) to veer off course, as you have likely personally experienced. The bowl-shaped adapter, however, better regulates the circulation from your hair drier when using a diffuser. This makes it easier for you to get the hairdo you’ve always wanted without using a curling wand or straightener afterward.
Is it harmful to blow-dry your hair? You now know that the response is sometimes an unmistakable one. Blow-drying your hair properly may be less difficult for your locks than air-drying. Ensure to include the advice mentioned earlier in your daily hair care and style regimen. Fortunately for everyone, promoting the look of healthy hair is simple to do by following these guidelines and using the best shampoo for thinning hair.
