Considered answers to real questions about hair loss, hair replacement, hair extensions, hair care and professional standards, written from Sandra Atoge's practice at iHobbs.
At every hair system maintenance appointment, I remove the system completely. It allows me to care for the natural hair, examine the attachment areas and decide whether the same system is still the right choice. Simply moving the beads up cannot replace that assessment.
A hair system can look natural, but I cannot guarantee that nobody will ever notice it. Suitability, specification, fitting, cut, blending and ongoing care all matter. Understanding those decisions is more useful than a promise of invisibility.
I would compare what you will learn, how your practical competence is assessed and who will guide you, not just the finished photographs or certificate. Before investing, get clear written answers about entry requirements, full costs, support and the exact credential and insurance suitability.
A smoothing treatment may reduce frizz, make styling easier and give hair a smoother appearance. I would not promise poker straight hair that needs no styling. The realistic result, suitability and safety questions depend on the exact product and your hair, not simply the word keratin.
Yes, hair extensions can damage your hair. Damage is not inevitable, but no method or professional fitting is risk free. I would look at the natural hair carrying the extensions, the load and tension involved, and the plan for care, maintenance and removal before judging whether they are suitable.
