What causes dull hair?
The cuticle scales of healthy hair usually lie flat and are tightly interlocked with each other around the hair shaft. This creates a smooth surface, allowing your hair to reflect light like a mirror.
When hair is dull, these cuticles become rough and uneven and can no longer perform their natural protective function. As hair is repeatedly exposed to blow dryers, flat irons, chemical products, pollution, dust, and sunlight, it is no longer protected from these external factors and becomes increasingly fragile.
The result is dull hair that no longer reflects light as it should. Raised cuticles also make the hair shaft more porous, meaning your hair is unable to retain moisture or benefit from hair products. So your hair can become dehydrated, brittle, coarse, and difficult to style—not to mention losing its shine!
Shiny hair isn't just the result of applying a product to the surface. It comes from consistent care, gentle brushing, and maintaining a healthy scalp.
How can you make your hair look shinier?
Achieving salon-quality shine is as simple as incorporating a few basic hair care habits into your routine.
1. Use a boar-bristle hairbrush to brush your hair
There’s really nothing like a boar bristle brush for bringing out unparalleled shine. This is because the fibrous structure of boar bristles is perfectly suited to lifting the natural oils produced by the scalp and distributing them evenly from root to tip, nourishing the hair and giving it an instant glossy look. The Repair & Shine brushes from Altesse Studio are the perfect tools for the job. Available in two sizes—one for fine to normal hair and the other for thick or curly hair—these brushes are specially designed to restore shine to the hair shaft and reveal your hair’s natural luster. No wonder 92% of our customers report that their hair has become shinier with regular use! (RS Développement study, February 2022)
Pro tip: Brush your hair every evening for extra shine. Make sure it’s dry when you do so, and for a complete, natural conditioning routine, try the 100-stroke brushing technique.
2. Rinse your hair with cold water for a shiny, silky finish
This tip isn't for the faint of heart, but cold water is your best friend when it comes to keeping your hair shiny. Hot water weakens the hair shaft and can even stimulate the sebaceous glands in your scalp, making it more prone to oiliness. Rinsing your hair with cold water helps prevent this by sealing the cuticles—which, as we mentioned, is the secret to achieving a mirror-like shine!
However, it’s important to remember that cold water isn’t effective at rinsing out the fatty oils found in conditioners and hair masks. To ensure you remove all unwanted residue that could make your hair look even duller, rinse out these products with lukewarm water before finishing with a quick cold rinse for a shiny finish.
3. Wash your hair less often to make dull hair shine
It goes without saying that you need to wash your hair to remove the buildup that accumulates over time, but it’s important to remember that shampoos contain surfactants, which, when used too frequently, can disrupt your scalp’s natural sebum production. This can lead to dryness, scalp discomfort such as itching, irritation, and dandruff, or even cause your hair to get greasy too quickly.
Washing your hair less often doesn't mean neglecting it. In fact, daily brushing helps remove some of the impurities that build up throughout the day while helping to distribute natural oils more evenly throughout the hair. The roots feel less weighed down, the lengths stay better protected, and the hair gradually regains a healthier, more natural-looking shine.
This rebalancing process requires consistency: a brushing session in the evening to help cleanse the hair, followed by gentler brushing in the morning to smooth, style, and restore shine.
For long-lasting shine and healthy hair, it’s best to space out your wash days and shampoo your hair only 2 or 3 times a week. To help your hair adjust to less frequent washing, a transitional period during which you brush your hair twice a day with a boar bristle brush can be helpful in keeping it clean and free of debris. This will also have the added benefit of keeping your hair naturally nourished and healthy by gently and evenly distributing the sebum produced by your scalp throughout your hair.
Bringing back shine starts with simple habits practiced consistently: smoothing the hair cuticle, caring for the scalp, spacing out wash days when possible, and choosing a brush that helps distribute natural oils from roots to ends. This is the essence of Altesse Studiocare brushing: revealing the hair’s natural radiance without weighing it down.
