hair pluckability protein nutritional status

Studysummary This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

Research cited in this study

9 / 9 results

research Telogen Effluvium: Causes, Diagnosis, and Treatment

144 citations , July 2002 in “Clinical and Experimental Dermatology”

This article reviews the concept of telogen effluvium and emphasizes the importance of identifying triggers and using diagnostic investigations to determine the cause of hair loss, without reporting new results.

research Nutritional Factors and Hair Loss

239 citations , July 2002 in “Clinical and Experimental Dermatology”

This review explores the role of nutritional factors in hair loss, noting that iron and l-lysine supplementation may benefit some individuals, while excessive supplements can lead to hair shedding.

research Diseases of the Hair and Scalp

189 citations , May 1991 in “Medical Entomology and Zoology”

This abstract lists chapters on various hair and scalp conditions and treatments but reports no new research findings.

research Field Use of Hair Epilation Force in Nutrition Status Assessment

14 citations , February 1982 in “American Journal of Clinical Nutrition”

This study observed that Nigerians with lower serum albumin levels had a significantly reduced hair epilation force, suggesting that hair pluckability might indicate protein depletion rather than energy depletion.

research Trichotillometry: The Quantitation of Hair Pluckability as a Method of Nutritional Assessment

17 citations , October 1981 in “American Journal of Clinical Nutrition”

This study found that individuals with protein-calorie malnutrition, especially those with kwashiorkor, required significantly less force to pluck hair compared to well-nourished patients.

research Alopecia in Crash Dieters

32 citations , June 1976 in “JAMA”

In this study, nine individuals who underwent rigorous weight loss programs experienced significant hair loss, which researchers attributed to insufficient energy supply to the hair matrix, with regrowth occurring within months.

research Alopecia in Crash Dieters

23 citations , June 1976 in “PubMed”

This study observed that crash dieting led to significant hair loss in patients, with hair regrowth occurring several months after the diet.

research Telogen Effluvium Secondary to Starvation Diet

11 citations , May 1976 in “Archives of Dermatology”

This report describes a case of probable telogen effluvium associated with stress and recent relocation, contributing to evidence of hair loss linked to weight reduction programs.

research Letter: Telogen Effluvium Secondary to Starvation Diet

4 citations , May 1976 in “Archives of Dermatology”

Starvation diets can cause significant hair loss.
