@rhea.jeong: This client discovered my Hair ASMR on Instagram and visited from Yangju. Her long, previously heat-permed hair felt coarse. My Own Formula Language Formulation is like seasoning: what I expect to need a "7" may respond to a "2." These illustrate intensity, not pH. Coarse texture does not always mean strong chemical resistance. Study, strand tests, and records help refine my first impression. I assessed roots, mid-lengths, and ends separately, tailoring mixing ratios and timing, with gentler care for treated lengths. Where supported by the product system, I adjusted pH while considering reducing strength, elasticity, and treatment history. The aim is effective softening while preserving remaining strength. Pro Tip for Hairstylists Record products, ratios, application order, processing times, strand-test responses, and follow-up results. Measure pH when appropriate; ratios alone do not reveal it. Use manufacturer-supported combinations. Lower pH is not automatically better, and strand tests cannot guarantee results. Softening lays the foundation. Iron temperature, contact time, tension, speed, repetitions, and correct neutralization must work together. Her hair finished soft and silky. In her five-star Naver review, she appreciated the tailored care and explanations, enjoyed filming, and said she wanted to return. Thank you for your trust. I will keep learning and caring for every visit. Rhea Jeong | 27 years behind the chair 11,500+ videos across YouTube, Instagram & TikTok, personally filmed, edited & uploaded.
