A viral TikTok video by content creator Kaley (@allthingskaley) has set the internet abuzz with a contentious theory: the risk of developing “hair mold” from not blow-drying your hair immediately after a shower.
Garnering over 18 million views and half a million likes, the clip has sparked a heated discussion among viewers, experts, and hairstyling enthusiasts alike.
The Video That Started It All
In the brief video posted on November 2, Kaley is seen blow-drying her hair while the caption warns: “Forever blow drying my hair as soon as I get out of the shower so I don’t get mold.” She added a playful caption: “Have you heard of hair mold? I’m actually terrified now.”
Kaley told Newsweek the video was meant as a lighthearted take on a trend she observed, admitting she doesn’t genuinely fear hair mold. “After researching, I realized my hair care routine doesn’t create conditions for this type of growth,” she said.
What Is “Hair Mold”?
Though the term “hair mold” itself is a misnomer, the video sparked legitimate concerns about scalp health. Harvard-trained dermatologist Dr. Roger Kapoor and hair transplant surgeon Dr. Ross Kopelman both confirmed that mold does not grow on hair under normal circumstances.
“Hair is made of keratin, which doesn’t easily support mold growth,” explained Dr. Kopelman. However, both experts noted that prolonged moisture on the scalp can lead to an overgrowth of natural fungi, like Malassezia, causing irritation, odor, or even hair breakage if left unchecked.
Dr. Kapoor emphasized: “The key is to let your hair dry completely to prevent trapping moisture on your scalp. This ensures a healthy environment.”
Social Media Reacts
Kaley’s TikTok comments section has been a battleground of opinions, ranging from horror to humor. While some users claimed personal experiences with scalp issues, others dismissed the concept as paranoia.
One commenter wrote, “WHAT IS HAIR MOLD?” in all caps, while another reassured viewers, “You’ll only get it if you let dead cells accumulate and don’t shower regularly.”
Kaley, however, has stepped back from responding to comments due to the overwhelming volume, including some harsh personal attacks.
Expert Tips on Scalp and Hair Health
For those worried about proper hair care, Dr. Kopelman offered practical advice:
- Wash regularly to keep the scalp clean.
- Avoid tight hairstyles when the hair is wet.
- Allow hair to dry completely, whether by air or blow-drying.
He reassured readers: “Air-drying is great, as long as you’re not in a rush and let your hair dry fully before tying it back.”
Kaley also clarified her own careful routine, which includes waiting 30–60 minutes post-shower before using a heat protectant and drying her hair on medium or low heat to avoid damage.
The Takeaway
While Kaley’s video may have started as a joke, it has highlighted a genuine discussion about hair and scalp health. Experts agree that keeping your scalp clean and ensuring hair dries properly—whether naturally or with a blow dryer—is key to avoiding irritation and keeping your locks healthy.
So, while there’s no need to panic about “hair mold,” Kaley’s viral moment has reminded us all of the importance of a solid hair care routine.
