TikToker Sparks Debate Over Blow-Drying Hair to Prevent ‘Hair Mold’
A TikTok creator has gone viral after sharing why she’s committed to blow-drying her hair immediately after getting it wet. Kaley Mosier (@allthingskaley) revealed in her video that her top priority post-shower is avoiding what she referred to as “hair mold.”
“Forever blow-drying my hair as soon as I get out of the shower so I don’t get mold,” Mosier wrote in the on-screen text of her video.
In the caption, she posed a question to her audience: “Have you heard of hair mold? I’m actually terrified now.” The video, which has garnered over 14.5 million views, has sparked widespread discussion about the concept.
Is ‘Hair Mold’ Real?
While the term “hair mold” itself is misleading, the science behind Mosier’s concerns isn’t entirely off base. Mold doesn’t grow on human hair, but hair-related fungal infections are possible—particularly on the scalp.
Fungi can thrive in environments where prolonged moisture and poor hygiene create an ideal breeding ground. According to The Mestiza Muse, factors like excessive sebum, covering damp hair, and leaving the scalp consistently moist can contribute to fungal growth.
The scalp is naturally prone to fungus and yeast infections due to its moist nature, the site explains, but these fungi differ from the types found on spoiled food. Indicators of scalp fungal infections can include:
- Unpleasant odors
- Yellow patches on the scalp
- Dandruff buildup
That said, experts caution against panic. As Women.com notes, getting your hair wet won’t necessarily lead to fungal infections. However, it’s wise to practice proper hair care by avoiding going to bed with wet hair, drying your hair after workouts, and maintaining good scalp hygiene. Using plant-based oils may also help combat fungal growth.
Mixed Reactions From Viewers
TikTok users had plenty to say about Mosier’s video, with opinions split between skepticism and caution.
Skeptics Push Back
Some commenters dismissed the notion of needing to blow-dry hair to prevent issues:
- “That’s how you get your hair to look like hay,” one person argued.
- “You’ll only get hair mold if you let dead cells accumulate in your hair, and anyone with a normal shower routine wouldn’t,” another remarked.
- “40 years of wet hair—nothing,” a long-time air-dryer said.
Others pointed out that fungal growth is rare and usually tied to extreme circumstances:
- “You only get mold if you have extensions and don’t dry them completely,” one hairstylist commented.
- “It takes 24 hours for mold to grow. Air drying your hair is fine if you don’t keep it tied up,” another explained.
Supporters of the Routine
Despite the pushback, others appreciated Mosier’s cautionary tale, saying they would reconsider their own routines. “Maybe it’s time to dust off my blow dryer,” one viewer admitted.
The Verdict: Should You Blow-Dry Your Hair?
While the fear of “hair mold” may be exaggerated, the conversation raises important points about scalp health. Ensuring your hair is dry, especially before tying it up or going to bed, can help prevent fungal growth. For those concerned about heat damage, alternatives like microfiber towels or diffusers can help speed up drying without harming your hair.
At the end of the day, whether you stick to air-drying or reach for your blow-dryer, your hair care routine should reflect what works best for your lifestyle—and your peace of mind.
