Hair dryers are commonly used and can cause hair damage such as roughness, dryness and loss of hair color. It is important to understand the best way to dry hair without causing damage.
The study assessed changes in the ultra-structure, morphology, moisture content, and color of hair after repeated shampooing and drying with a hair dryer at a range of temperatures.
A standardized drying time was used to completely dry each hair tress, and each tress was treated a total of 30 times. Air flow was set on the hair dryer. The tresses were divided into the following five test groups: (a) no treatment, (b) drying without using a hair dryer (room temperature, 20ž), (c) drying with a hair dryer for 60 seconds at a distance of 15 cm (47ž), (d) drying with a hair dryer for 30 seconds at a distance of 10 cm (61ž), (e) drying with a hair dryer for 15 seconds at a distance of 5 cm (95ž). Scanning and transmission electron microscopy (TEM) and lipid TEM were performed. Water content was analyzed by a halogen moisture analyzer and hair color was measured with a spectrophotometer.
Hair surfaces tended to become more damaged as the temperature increased. No cortex damage was ever noted, suggesting that the surface of hair might play a role as a barrier to prevent cortex damage. Cell membrane complex was damaged only in the naturally dried group without hair dryer. Moisture content decreased in all treated groups compared to the untreated control group. However, the differences in moisture content among the groups were not statistically significant. Drying under the ambient and 95ž conditions appeared to change hair color, especially into lightness, after just 10 treatments.
Although using a hair dryer causes more surface damage than natural drying, using a hair dryer at a distance of 15 cm with continuous motion causes less damage than drying hair naturally

Autoimmune, Atopic, and Mental Health Comorbid Conditions Associated With Alopecia Areata in the United States.
Huang KP, Mullangi S, Guo Y, Qureshi AA.
OBJECTIVE To evaluate the prevalence of comorbid conditions among patients with alopecia areata (AA) seen at tertiary care hospitals in Boston, Massachusetts, during an 11-year period. DESIGN Retrospective cross-sectional study. SETTING Tertiary care hospitals in Boston, including Brigham and Women's Hospital and Massachusetts General Hospital. PARTICIPANTS We identified 3568 individuals with AA seen in the Partners health care system in Boston between January 1, 2000, and January 1, 2011. We performed comprehensive searches of the Research Patient Data Repository using International Classification of Diseases, Ninth Revision code 704.01. We randomly selected 350 patients and manually reviewed their medical records to train and validate a novel artificial intelligence program. This program then used natural language processing to review free-text medical records and confirm a diagnosis of AA. To confirm the algorithm, we manually reviewed a subset of records and found 93.9% validity. MAIN OUTCOMES AND MEASURES The prevalence of comorbid conditions was assessed. RESULTS Common comorbid conditions included autoimmune diagnoses (thyroid disease in 14.6%, diabetes mellitus in 11.1%, inflammatory bowel disease in 6.3%, systemic lupus erythematosus in 4.3%, rheumatoid arthritis in 3.9%, and psoriasis and psoriatic arthritis in 2.0%), atopy (allergic rhinitis, asthma, and/or eczema in 38.2% and contact dermatitis and other eczema in 35.9%), and mental health problems (depression or anxiety in 25.5%). We also found high prevalences of hyperlipidemia (24.5%), hypertension (21.9%), and gastroesophageal reflux disease (17.3%). This profile was different from that seen in a comparison psoriasis and psoriatic arthritis group. CONCLUSIONS AND RELEVANCE We found a high prevalence of comorbid conditions among individuals with AA presenting to academic medical centers in Boston. Physicians caring for patients with AA should consider screening for comorbid conditions.

Adv Nurse Pract. 1999 Apr;7(4):39-42, 83. Hair-raising. The latest news on male-pattern baldness.
The initiating event in balding seems to be an abnormal sensitivity to the male sex hormones. In addition, a multifactorial model is emerging in which hormones affect the hair follicle in a way that causes it to be perceived as a foreign body by the immune system, which then mounts an attack. Several new classes of agents have the potential to treat hair loss. More than 40 U.S. and several hundred foreign patents have been issued for hair-loss treatment agents. As is common in dermatology, no single agent works universally against hair loss, so the treatment process is often one of trial and error.
