Phytochemicals from Dicerocaryum senecioides were studied for hair rejuvenation activity using BalB/c mice. Solvent extractions and thin layer chromatography (TLC) were used to extract and isolate the phytochemicals respectively. Phytochemicals were identi ed by spraying with target-speci c revealing reagents. In vivo hair growth stimulating activity for each extract was tested on denuded dorsal skin of 5-week old BalB/c mice against the controls and the standard drug minoxidil. e parameters used to evaluate hair growth were hair growth completion time, hair length, hair weight, hair follicle length, and relative hair follicle area. e identi ed phytochemicals from the active ethanol extract were steroidal glycosides, triterpenoid glycosides, and avonoid glycosides. Flavonoid glycosides treatment had the uppermost hair rejuvenation capacity as measured by the shortest hair growth completion time (19 days) versus control (29 days) and longest hair length (11.04 mm and 11.86 mm for male and female mice respectively while the control group had 5.15 mm for male mice and 5.33 mm for female mice). Hair growth stimulation by avonoid glycosides was also dependent on dose concentration. It can be concluded from this study that avonoid glycosides extracted from the leaves of Dicerocaryum senecioides have remarkable hair rejuvenation capacity in BalB/c mice. e present results provides insights on the use of Dicerocaryum senecioides for hair rejuvenation in traditional practices and on the potential of the plant as a source of novel compounds that can be used as hair growth promoters.
There are diverse types of alopecia and each call for a specific treatment. Regrettably there is no curative solution to the problem of alopecia as most drugs target its management. The purpose of the review is to explore the different types of alopecia and how each affect hair appearance and growth. The review begins by describing hair structure and hair physiological changes during life progression. A detailed description of conventional medication prescribed for alopecia and associated adverse effects are also pronounced in this review. Both approved (minoxidil and finasteride) and unapproved medications indicated for the condition are discussed to expose voids, which need to be filled by future drug development. The review also discusses the prospective future therapies of alopecia as directed by current research and technological advancement.
Background Different hair types respond differently to cosmetic treatments; hence, many options ought to be availed to the consumer. The purpose of this study was to evaluate the use of antioxidant extract from Dicerocaryum senecioides as active alternatives in hair semi‐permanent waving and hair conditioning. Methods The antioxidant phytochemicals were first identified and isolated by thin‐layer chromatography (TLC) and spraying with revealing agents. The antioxidant potency was determined by DPPH antiradical scavenging and ferric reducing power methods. The extract was incorporated in two different formulations to make the extract perm (bio‐semi‐permanent) and the antioxidant hair conditioner (AC). The formulations had their performance examined for hair curling and conditioning on Asian and African hair types. Hair damage was assessed by scanning the surface of treated samples on an attenuated total reflectance–Fourier transform infrared spectrometer (ATR‐FTIR) and by quantifying lost protein on ultraviolet visible (UV‐Vis) spectrophotometer. Results The extract antioxidant had an IC50 of 26.54 ± 0.34 µg/ml exhibiting greater antioxidant potency compared to the controls quercetin (38.84 ± 0.12 µg/ml) and ascorbic acid (35.22 ± 0.07 µg/ml). The extract perm had a lower curling ability indicated by a perm set of 85.10 ± 3.92% and 81.35 ± 2.35% for Asian and African hairs, respectively, while commercial product, ammonium thioglycolate (ATG) had 96.05 ± 1.70% and 93.60 ± 2.21% for the same. The curling of hair with extract perm resulted in less oxidative damage with oxidative peak areas of 3.37 ± 0.09 and 3.71 ± 0.03 as well as lower protein losses of 4.72 ± 0.71 µg/mg and 5.62 ± 0.70 µg/mg on Asian and African hair samples, respectively. The application of AC reduced the oxidative damage peak areas of ATG and extract perm treated Asian hair samples by 1.15 and 0.48 units, respectively. AC was also effective in reducing damage caused by UV radiation on ATG‐treated samples by 1.06 units (African hair) and 1.09 units on Asian hair. Conclusion The results show antioxidant extracts from Dicerocryum senecioides as a promising and safer alternative for hair conditioning and semi‐permanent curling.
