Make your hair the SHINIEST and SOFTEST it’s ever been
What exactly is shiny hair and how do we achieve this facet?
Shiny hair is hair that reflects more light.
Reflection of light is either specular (mirror-like, smooth surface) or diffuse (retaining the energy, rough surface) depending on the nature of the interface.
The laws of reflection are as follows:
- The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
- The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.
- The reflected ray and the incident ray are on the opposite sides of the normal.
These three laws can all be derived from the Fresnel equations.
The picture below describes the phenomena in which an incident ray will yield the same degree of angle as the reflected when incident upon a medium or any mirrored surface. The second diagram you see below represents an unshiny hair strand. Reflection plays out differently in this case, where the hair is virtually not shiny. This is what we do not want!
In theory, you would like your hair to be specular.
Looking at the cuticle up close, we can see that the healthiest cuticle looks quite closed and well defined (closer to be specular).
For many reasons our hair can be open, raised, damaged, all of which make the surface of your hair more rough and less shiny. These pictures below feature a damaged cuticle with ridges pointing upwards at greater stages of impairment.
Some of you will ask me “how come my hair is shiny when its wet?” Normally an open cuticle will diffuse reflection due to its rough surface, however if the surface is wet, water can fill in the crevices and smooth out the surface. Rays of light from your apartment or perhaps the sun hits this new smooth surface/medium and reflection from the incident ray will result making the cuticle more specular and shiny.
Using the right equipment to blow dry your hair will sufficiently temporary correct a damaged cuticle to a closed cuticle. This is important!
Attach the nozzle to your blow-dryer, and only point the airflow down on your hair from above; this smooths the cuticle as you dry, leaving hair shinier.
If some of those cuticles are damaged, your hair could benefit by applying some heat activated cream before blow drying. “Ciment Thermique” is a popular product of the French brand Kerastase that acts to fill in the crevices on the cuticle. The surface of your hair will be smoother until the next shampoo.
Gloss done in salon could also help make your hair more shiny, but don’t get fooled… Gloss DOES NOT repair your hair; I’ve heard that lie too many times.
A gloss or toner is a semi-permanent coloring (clear or colored) with very low peroxide and no ammonia. The injected pigment stays mostly on the cuticle of the hair helping fill the gap which is the same way a heat activated cream would respond but is resistant to shampoo which makes it much more durable.

In summary, what are the BEST KEPT SECRETS for the shiniest hair:
- Prevention (keep your hair away from cuticle damage)
- Use the right products
- Blow dry you hair properly
