The scanning electron microscope (SEM) was successfully used to study the effects
of toiletry treatment with shampoo on the microstructure of hair. This paper
describes the use of SEM for comparing the conditioning effects of herbal
shampoos. Commercially available herbal shampoos are not completely natural, but
contain herbal extracts in a synthetic detergent base, along with other chemical
additives. Completely natural shampoos were formulated in the laboratory and
their conditioning effects were evaluated by comparing with a commercially
available herbal shampoo. The micrographs were studied quantitatively using
‘Image Analyser Software’ and the extent to which the hair scales were uplifted
was measured. The results obtained from the quantitative comparison were in
agreement with those obtained from other tests, such as protein loss
determination. The damage caused to the hair due to sodium lauryl sulphate was
visible in the micrographs. The laboratory formulations were found to be better
than the commercially available product. Thus, quantitative measurements from SEM
micrographs are a valuable tool to compare the conditioning effects of hair care
products.

Hair growth promoting activity of Eclipta alba in male albino rats.Roy RK, Thakur M, Dixit VK.

Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Eclipta alba Hassk. is a well-known Ayurvedic herb with purported claims of hair growth promotion. In the reported work attempts were undertaken to evaluate petroleum ether and ethanol extract of E. alba Hassk. for their effect on promoting hair growth in albino rats. The extracts were incorporated into oleaginous cream (water in oil cream base) and applied topically on shaved denuded skin of albino rats. The time (in days) required for hair growth initiation as well as completion of hair growth cycle was recorded. Minoxidil 2% solution was applied topically and served as positive control for comparison. Hair growth initiation time was significantly reduced to half on treatment with the extracts, as compared to control animals. The time required for complete hair growth was also significantly reduced. Quantitative analysis of hair growth after treatment with petroleum ether extract (5%) exhibited greater number of hair follicles in anagenic phase (69 +/- 4) which were higher as compared to control (47 +/- 13). The result of treatment with 2 and 5% petroleum ether extracts were better than the positive control minoxidil 2% treatment.
