Until now there was no method of measuring the normal daily hair loss recognized worldwide, to determine if a person starts to go bald, or if the amount of hair loss is normal. It often indicates that it is normal to lose up to 100 hairs a day, a figure based on the assumption that an average scalp has about 100,000 hair. Scientifically, the number of 100 hairs per day has not yet been proven. It does not take into account the consistency or otherwise of hair loss in life, any more than if this number is the same for men and women. Researchers from the Universities of Texas, Maryland and Pennsylvania have now designed a scientific practical test to quantify the normal hair loss in men. In their study, they combed through the hair loss of sixty white men in good health, without signs of baldness. Half of those in the sample were aged 20 to 40, the other half from 41 to 60 years. All men of the same test using a comb and washed their hair three mornings in a row with the same shampoo. The fourth, fifth and sixth morning, the scientists asked them to comb their hair for 60 seconds over a towel in a contrasting color.
60 seconds of combing
The results showed that young men lose an average of 10.2 hairs per 60 seconds of combing. Extreme values are 0 to 78 hairs. Older men lost an average of 10.3 hairs per test, with extreme values of 0 and 43 hair. Six months later, during a rehearsal of the study, similar results were observed in both age groups. In addition, the counting was not done this time by the persons in the sample, but by scientists. Scientists believe the small difference in the results of two tests, both in young men than among older test proves that the capillary 60 seconds is a simple, convenient and reliable to determine if it is a normal or hair loss problem. This hair loss differed from the average results of a previous study, which reached an average of 44 hairs. The researchers speculate that the use of shampoo explains this difference, and a spacing between the teeth of the comb teeth and a thickness of others. The next step which will tackle the scientists is the repetition of the test combing hair in women, men suffering from baldness, people of different ethnic origin and people with other forms of loss hair.
