Nine patterns to recognize
I group common problems into nine practical patterns: chemical stress, heat stress, mechanical wear, high porosity, split ends, breakage, dryness, persistent frizz, and environmental buildup or weathering. Several can appear together.
This is an educational framework, not nine formal medical diagnoses. Scalp inflammation, sudden shedding or unexplained patchy hair loss need assessment by an appropriate medical professional, not just a salon treatment.
02 / THE DETAILS
What happens to the fibre
The cuticle helps protect the cortex beneath it. Bleaching can affect both the surface and internal keratin; friction and heat can progressively wear protective layers. Porosity and elasticity tests provide clues, but no single visual test tells the complete chemical history of a strand.
Research on hair damage describes changes in surface morphology, fibre strength and protein structure. The key lesson is that the source of damage matters when choosing how to care for it.
03 / THE DETAILS
Match the plan to the problem
For friction and tangling, focus on gentle handling, conditioning and reducing unnecessary brushing. For heat stress, consider styling temperature and frequency. For colour-related weakness, discuss further chemical processing cautiously and select aftercare suitable for the condition.
A trim can remove visibly split ends; no bottle permanently glues them back into virgin hair. The right plan is often a combination of small changes rather than an expensive miracle treatment.
