[Determination of specific weight of the pigmented, grey and thick hairs from head].
The hair of man is one of the complicated objects of investigation in forensic medicine expertise. The purpose of this research was to determine the significance of specific gravity of grey, pigmented, thin and thick hairs from head in identification of personality. The specific gravity and diameter of 10 grey, 10 pigmented and 10 thick and 10 thin hairs were investigated in seven men. The diameter of the hair plays a significant role in determination of the body area from which the hair may have arisen. The obtained data were statistically analyzed. The specific gravity fluctuations of grey hair in each of investigated persons was: 0,58-0,65; 1,81-1,92; 1,26-1,33; 0,86-0,92; 1,56-1,66; 2,25-2,34; 2,00-2,08 10(4) H/m(3). The specific gravity fluctuations of pigmented hair in each of seven persons was: 0,57-0,64; 1,80-1,92; 1,27-1,37; 0,87-0,93; 1,57-1,66; 2,26-2,34; 1,99-2,08 10(4) H/m(3). It was concluded that establishment of specific gravity of grey and pigmented hairs from head is vital for forensic medicine.
