Clinical Trial Summary

Hair appearance is an important issue for females. Treatment of hair with keratin has been popular among females nowadays. Although chemical hair straightening application has a beneficial effect on hair shafts with the repair of the broken cuticle, some side effects may occur. Therefore, this study aims to study the efficacy and safety of such new non-formaldehyde widely used keratin treatments on hair by assessment of changes of the scalp, hair density, and the morphology, color, and ultrastructure of hair shaft after application.

Description:

Hair is an important feature for most women that contribute to one's individual identity. The appearance and morphology of the hair is one of the divergent traits in humans. Keratin in hair care products has two effects; it can penetrate the cortex of the hair fiber improving the mechanical properties of damaged fibers and promotes a surface coating that prevents or decreases water diffusion through the hair fibers.These properties have beneficial effects on the hair structure replacing lost keratin.However, the side effects and safety of this treatment have not yet been completely evaluated.There are many different brands of the keratin hair treatment, all with nearly the same basic chemical composition. Non-formaldehyde containing keratin straightening products, also known as safe keratin treatments (SKT) have recently been introduced to the market.Therefore, this study aims to study the efficacy and safety of such new non formaldehyde widely used keratin treatments on hair.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of hair shedding using the Visual analogue scale (VAS)	It will be used to evaluate hair shedding. Hair shedding is scored on a scale of 1-6. Women are asked to look at the scale and point to the photograph that best correlates with the amount of hair shed on an average day. Grades 1-3 are considered normal. Grade 4 is borderline, while Grades 5 and 6 indicate excessive shedding.	Baseline, 2 months, 4 months, 6 months
Primary	Change of hair morphology using trichoscope	It will be used to evaluate hair structure and scalp. Hair density/cm 2 and thickness (mm) will be measured in the frontal, temporal and vertex areas in all participants.	Baseline, 2 months, 4 months, 6 months
Primary	Change of hair morphology using Transmission Electron Microscopic examination	Randomly selected samples of each group will be fixed in 3% glutaraldehyde for over a period of 4 hours at 4°C and processed to be examined by transmission electron microscope	Baseline, 2 months, 4 months, 6 months
Primary	Safety evaluation	to detect any side effects that will be reported either by the patient or by the physician.	at 6 months
Secondary	Change of patient satisfaction questionnaire about keratin treatment	A 5 items Questionnaire will be completed by the patients to evaluate their satisfaction about the treatment. The questionnaire consists of Q1 (1-5), Q2,3 (1-7), Q4 (1-4) and Q5 has 3 sub-items Q5a, Q5b, Q5c (1-5 for each). Total score ranges from 7-38. Higher scores are associated with higher dissatisfaction.	Baseline, 2 months, 4 months, 6 months
