Preparing the hair follicle canal for hair shaft emergence
Experimental Dermatology, 2020AbstractThe emergence of hair is a defining event during mammalian skin development, but the cellular mechanisms leading to the opening of the hair follicle canal remain poorly characterized. Our previous studies have shown that early hair buds possess a central column of differentiated keratinocytes expressing Keratin 79 (K79), which marks the future ...

Minigraft Preparation in Surgical Hair Replacement
Scandinavian Journal of Plastic and Reconstructive Surgery and Hand Surgery, 1997A 38-year-old man with Norwood type V male pattern baldness underwent hair restoration surgery using a new technique aimed to minimise the time spent on cutting minigrafts by using a multibladed knife. A total of 600 minigrafts were harvested from the occipital region, prepared, and inserted into the bald area.

Preparation of Hair for Lead Analysis
Archives of Environmental Health: An International Journal, 1974A comparison of the washing procedures for hair samples for lead analyses was made. An ethylenediaminetetraacetic acid (EDTA) washing procedure proved best to eliminate the surface lead contamination of hair; neither the detergent nor hot ether washing procedures performed as well. Absorption of surface- bound lead into the hair shaft was not observed.

Bromate Poisoning From Hair Permanent Preparations
Pediatrics, 1985Potassium bromate is a tasteless, odorless, and colorless chemical found in the neutralizing solution of cold wave home hair permanents and profesional solutions. Toxic ingestions of this substance were initially reported during the 1940s and 1950s and are characterized primarily by gastrointestinal symptoms, hearing impairment, and acute renal failure.

Acute Airway Responses to Hair-Spray Preparations
New England Journal of Medicine, 1974Abstract Acute exposures (20 seconds) to hair-spray preparations A, B and C caused significant decreases of maximum expiratory flow rates at low lung volumes in healthy men and women. Peak expiratory flow rates were reduced slightly after hair spray A only. The decreases were more pronounced on partial than on maximal expiratory flow-volume curves.

Herbal preparations for the treatment of hair loss
Archives of Dermatological Research, 2019Though hair does not serve any crucial physiological function in modern humans, it plays an important role in our self-esteem. Androgenic baldness (androgenic alopecia) and circular/spot baldness (alopecia areata) are the most common forms of hair loss. Many active ingredients of synthetic origin are available for treatment; however, they have a number

Preparation of hair follicle germs using centrifugal forces for hair regenerative medicine
Journal of Bioscience and BioengineeringHair regenerative medicine presents a potential approach to treat hair loss. Mesenchymal and epithelial cells may be transplanted to regenerate de novo hair follicles, as epithelial-mesenchymal interactions are crucial for hair follicle morphogenesis.
