Some also doubt whether it is better to put the fabric softener or the shampoo first.
Drying hair is also a source of many doubts and now the doctor Leire Barrutia, specialized in dermatology and aesthetics and known for its informative channel in TikTok @demispherewanted to address whether it is better to let your hair dry in the open air or use a dryer. Its publication, from a week ago, exceeds 40,000 views.
«Dryer or open air?»
«What is the best way to dry your hair according to science? Better with a dryer or better outdoors?», she asks herself at the beginning of the publication. To answer this question, she looks at a scientific study published at the end of 2011 that analyzed precisely how a dryer can damage hair.
As she highlights from the research, “the healthiest way” to dry your hair is to do it “with a hairdryer.” The study goes deeper and establishes that it must be done 15 centimeters from the hair and at a low temperature. «It is something that usually surprises. In general, we always think that it is better to dry our hair outdoors,” the dermatologist points out.
As she herself explains, using these parameters of distance and temperature, “we make sure that we do not have the wet scalp for a long time, which could favor changes in the flora of the scalp and the appearance of conditions such as seborrheic dermatitis. Dr. Barrutia warns that some profiles are predisposed to suffering from this disease and goes further in her defense of the hairdryer.
«In addition, when drying the hair with the dryer we remove the fragility surface of the hair, we seal the cuticle a little and this makes it look more beautiful,” adds the expert at the end of her video. In the comments, an Internet user with curly hair asked her how she should do it with the diffuser (which is usually used attached to the hair) and Dr. Barrutia stressed that she should use it but “at a low temperature.” Another expert in the medical sector has agreed with her and has remarked that “when we say it, they don’t believe us.”
