What You Need for a Trichology Consultation

Light microsocopy can be a useful clinical tool. It is especially relevant for the diagnosis of hair disorders that affect the hair shaft (e.g., genodermatosis) or pathologies in which there is deposition of substances on the hair shafts (e.g., pediculosis capitis). Generally, the hair sample to be analyzed is collected by either clipping or plucking. Hair clipping can be performed with straight Mayo scissors, whereas plucking is usually done with rubber-protected forceps. Although the use of the microscope in a trichology clinic has declined since the advent of trichoscopy, it is still a particularly useful device for the initial clinical orientation of genodermatoses. In addition, it is usually necessary for the realization of a correct trichogram. The complementary techniques to light microscopy are polarizing microscopy (especially useful if trichothiodystrophy is suspected) and scanning electron microscopy. These devices are not usually necessary in a standard trichology consultation.
The upper third of the face

To further improve the aesthetics of the brow, reshaping with botulinum toxin and fillers in the adjacent areas (temples, forehead) can be considered. Also, advice can be given on plucking or not plucking of the brow. See also Figure 5.16.
Tissue Grafting Techniques
Published in Vineet Relhan, Vijay Kumar Garg, Sneha Ghunawat, Khushbu Mahajan, Comprehensive Textbook on Vitiligo, 2020
As noted earlier, it has been observed that plucking the hair with forceps after giving anesthesia delays hair growth and prevents the graft from being lifted up. Hence plucking the hairs instead of shaving them to avoid graft displacement is recommended [22]. Chemical epilation is an alternative to plucking of hair [23].

Although the preferred body regions in hair/hair pulling vary in terms of clinical features, the most preferred region is the scalp, and the rates of extra-cranial pulled areas were found to be significantly lower [5,7,16,17]. In The Child and Adolescent TTM Impact Project (CA-TIP) survey study by Franklin et al., in which they evaluated 133 young people aged 10–17 years examining the life-long hair/hair pulling characteristics in individuals with TTM, the most common areas of hair/hair plucking were found to be the scalp with 85.7%, eyelashes with 51.9% and eyebrows with 38.3%; however, pubic hair pulling was reported to be much higher than that reported in other studies [8]. In our study, the sequence of the plucked regions was similar to the previous studies, as the scalp, eyelashes, eyebrows, and other regions, respectively, and the rate of pubic plucking was found to be very low.
To Shave or Not to Shave: Exploring Pubic Hair Removal among College Students
Published in American Journal of Sexuality Education, 2022
Students were asked to indicate the method(s) they used to remove their pubic hair from a list including razor, trimmers/clippers, scissors, wax, plucking and other (e.g., laser, depilatory cream). The razor was used by most students (86.3%) to remove their pubic hair. This was followed by trimmers/clippers (20.9%), scissors (13.7%), waxing (7.9%), and plucking (7.6%). Other methods such as laser or depilatory cream were rarely used (1.8%). Significant differences in methods used to remove pubic hair were found between men and women (X2 = 71.46, df = 5, p = 0.000). The most frequent method cited by women was the razor (99.0%); less frequent methods included scissors (1.9%), waxing (9.9%), plucking (8.9%), and trimmers/clippers (7.9%). Men most frequently used a razor (57.6%), but also were more likely to say they used trimmers/clippers (50.6%) or scissors (20%).
Extracting the elasticity of the human skin in microscale and in-vivo from atomic force microscopy experiments using viscoelastic models

The skin surface at the micro scale looks like an uneven moving surface due to motion of the skin due to heart beat, small ridges that form the fingerprint, sweat pores, wrinkles (Schultz et al. 2018) and hair follicles. The viscoelastic models, however, are derived for a flat and fixed materials. The motion of the skin due to heart beep was addressed by using a combination of using a high indentation speed of 40 n = 10 many experiments were conducted at each location and also on different locations on fingertip. The unnormal force-indentation curves, caused by indenting on ridges that form fingerprint, wrinkles, sweat pores, were removed. For testing other body sites where hair grows, hair can be either removed or clipped to provide access to a small area of skin about 2 × 2 mm. Shaving scrape the skin and remove some of the cells from SC layer. The plucking result in local skin inflammation. As a result, shaving or plucking the hairs might change the skin mechanics and thus are not recommended for removing hairs before the tests.
