ABSTRACTObjectives: We evaluated the correlation between metric parameters and laboratory assessments of hair taken from patients undergoing oral supplementation of orthosilicic acid. Material and methods: 34 women aged between 17 and 57 years received an oral dose of 30 mg of orthosilicic acid for five months. Hair samples (pre and post-treatment) were obtained from an area of 1 cm² on the occipital protuberance and submitted to ultrasound bath in a distilled water solution. After that, we tested this water using spectrophotometric technique for measuring the hair ability to preserve proteins during physical stress. Hair growth was also assessed every month, before treatment and during treatment. We applied a questionnaire addressing the perception of patients about their hair. Results: 83% of patients believed that there was overall improvement of hair quality after treatment. 79.41% of patients exhibited increasing in hair growth rate and this increase was of 37.6%. Protein loss analysis showed a improvement in hair quality. Conclusion: We suggest that orthosilicic acid has a beneficial role in the hair, leading to a faster growth rate and an increase in resistance to aggression.
