The products for hairs and hair roots are produced from nano-colloid Citrus hystrix leaf extracts, by one more plant extract, Aloe vera is supplemented in Nat Hair Treatment.

@ Citrus hystrix has long been used for overcoming hair and root hair problems in delaying gray hair and anti-dandruff. Srisukh et al. (2012) reported that bergamot essential oil has activity in antibacterial caused diseases including Streptococcus pneumoniae, Haemophilus influenza, Streptococcus aureus and Acinetobacter baumannii. The major component of the leaf; and fruit oil are oil is 80.04% citronella; 40.65% limonene, 13.71% terpinene-4-ol, and 13.20% α-terpineol. The most active compounds are α-terpineol, followed by terpinene-4-ol and limonene. In addition, bergamot oil also gives a pleasant aroma.

@ Based on this knowledge, the SciSeeIt research team investigated β-sitosterol contained in kaffir lime leaves by gas chromatography- Flame Ionization Detector (GC-FID) method. The results showed a high concentration of 1.55 mg/ml and a high amount of 25 mg/g plants as shown by chromatograms at Rt = 16.80-16.81 min.  

@ β-sitosterol can inhibit the activity of the 5-α-reductase in the mechanism of converting testosterone to dihydrotestosterone (in which dihydrotestosterone will be accumulated at the hair follicle cells, making the hair roots weak and finally hair loss and the new hair grows smaller and smaller) so the hair roots are strong, no hair loss or if hair loss for any other reason new hair can grow from that root hair again. For quick absorption into the skin leading to high active efficiency, the kaffir lime leaf extract was passed through a high-pressure homogenizer making it into nanoparticles before being used in the production of hair products such as Nat Hair Serum, Nat Hair shampoo and Nat hair treatment.
