,
April 2002 in “Journal of The American Academy of Dermatology” In this study, finasteride, 1 mg daily, significantly increased hair weight more than hair count in men with androgenetic alopecia, indicating additional factors like hair growth rate and thickness may contribute to its effectiveness.
31 citations
,
August 2001 in “PubMed” This study found that the TrichoScan method detected significant increases in hair counts and cumulative hair thickness in men after finasteride treatment, suggesting its potential for monitoring hair treatment responses.
12 citations
,
August 2001 in “PubMed” This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.
41 citations
,
May 2001 in “PubMed” This study proposes a new clinical scoring method for hair density based on hair diameter diversity, which correlates with existing measures and reflects follicle miniaturization in androgenetic alopecia.
129 citations
,
October 2000 in “British Journal of Dermatology” This study found that finasteride increases anagen hair growth in men with androgenetic alopecia.

36 citations
,
January 1998 in “Journal of Dermatological Treatment” This study developed a standardized questionnaire to measure patient-perceived changes in hair growth and appearance, which showed significant favoring of active treatment over placebo in a clinical trial for male androgenetic alopecia.

August 1995 in “Australasian Journal of Dermatology” This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.
5 citations
,
January 1995 in “Journal of Investigative Dermatology” A trial found that using finasteride, a hair growth drug, can be effectively measured by comparing before and after photos.
19 citations
,
August 1993 in “Journal of Cutaneous Pathology” In this study, researchers found that as androgenetic alopecia severity increased, the hair follicle matrix and dermal papilla's volume and cell nuclei number decreased, especially in the papilla.
309 citations
,
May 1993 in “Journal of The American Academy of Dermatology” This study concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.

,
October 1992 in “JEADV. Journal of the European Academy of Dermatology and Venereology/Journal of the European Academy of Dermatology and Venereology” In this study, Scalp Immersion Proxigraphy (SIP) was shown to produce more accurate measurements of linear hair growth rate than crude phototrichogram techniques, suggesting SIP's suitability for clinical trials monitoring hair growth.
