Keratins are tough, fibrous proteins found as the major protein component in hair. Chemical hair removal is harsh and results severe toxicity pollution, hence, a need for non-chemical enzymatic process. The aim of this study to characterise keratinase from isolated keratin-degrading Bacillus licheniformis-K51, subtilis-K50 sp.-K53 investigate its potential removal. collagenolytic ability kerati...

We present two uncommon cases of adolescent girls with hair-thread strangulation of the labia minora. The first 14-year-old girl presented with a painful pedunculated labial lump (Fig. 1). The lesion was covered with exudate. She was examined under sedation and found a coil of long hair forming a tourniquet around a labial segment. Thread removal resulted to immediate relief from pain, and grad...

Several skin conditions are more common in persons with skin of color, including dermatosis papulosa nigra, pseudofolliculitis barbae, acne keloidalis nuchae, and keloids. Dermatosis papulosa nigra is a common benign condition characterized by skin lesions that do not require treatment, although several options are available for removal to address cosmetic concerns. Pseudofolliculitis barbae oc...

Brain tumors, which is one of the destructive forms of human being’s cancers, are the second most common children’s cancers. Brain tumors may have an inherited (small percent), acquired reasons due to environmental factors. Nowadays advances in cosmetic industry have increased our ability in the field of youth and beauty. Hair dye products are such innovations. Recent studies showed...

In hair cells of the inner ear, robust Ca2+/H+ exchange mediated by plasma-membrane Ca2+-ATPase would rapidly acidify mechanically sensitive hair bundles without efficient removal of H+. We found that, whereas the basolateral membrane of vestibular hair cells from the frog saccule extrudes H+ via an Na+-dependent mechanism, bundles rapidly remove H+ in the absence of Na+ and HCO3(-), even when ...

The post-transductional elaboration of sensory input at the frog semicircular canal has been studied by correlating the effects of drugs that interfere with phosphorylation processes on: (i) potassium conductances in isolated hair cell and (ii) transmitter release at the cytoneural junction in the intact labyrinth. At hair cells, delayed potassium currents (IKD) undergo voltage- and time-depend...

Laser- or flashlamp- (also called intense pulsed light source or IPLS) assisted hair removal is a well tolerated and effective technique for patients who desire permanent reduction of hair growth. Although laser and light sources are very popular because of their non-invasive nature and the speed at which they operate, practitioners and patients have to be cautious to avoid permanent side effec...

OBJECTIVE The main purpose of this clinical study was to compare the effectiveness of an intense pulsed light irradiator system (IPL) and a normal mode ruby laser for hair removal. MATERIALS AND METHODS Thirty-one patients were treated 3 times with a new IPL system on one side of the chin and neck and with a normal mode ruby laser on the other side. After 6 months, nine of the patients receiv...
