### Clinical Evaluation  
Regarding the investigator evaluation, scores ranged from 2 to 5 (\(p\) = 0.123), and 14 patients (70%) (8 males and 6 females), who underwent the LLLT reported good results regarding global scalp coverage and hair thickness (Figures 2B, 3B, and 5B) versus 6 patients (30%) (2 males and 4 females) with ineffective results. \begin{table}

Table 2: In vivo evaluation using trichoscopy analysis in terms of hair density (HD) (hairs/cm\({}^{2}\)) improvement. Regarding the patient evaluation, scores ranged from 1 to 4 (\(p\) = 0.031), and 17 patients (85%) (9 males and 8 females) indicated a good level of satisfaction regarding the global scalp coverage, versus only 3 patients (15%) (1 male and 2 females) who indicated ineffective results. The results reported show male patients as more satisfied than female patients.
