There are so many confusing topics out there regarding hair. Here you can find your questions answered with a scientific explanation. Here are 5 of the many questions people wonder about.
1. Can protein treatments repair my hair?
Unfortunately the answer is no. Hair once it grows out from the follicle is no longer a living organism with live cells. Once the damage is done to the hair, the hair cannot heal itself like skin would. Protein treatments are great for those who need it to add some body to hair, strength, help in retaining moisture etc. They have numerous benefits and can prevent further damage. However, that’s all they do. [More about protein treatments here]
2. Does cutting hair make hair grow faster?
You find that your hair seems to grow longer once you’ve cut your hair? Cutting hair doesn’t actually make your hair grow faster. The rate of hair growth is about 6 inches or 15 cm per year depending on the person and is not affected by hair cuts. What is actually happening is that by cutting your hair, you are getting rid of your split ends. Split ends have been known to cause further fissures along the hair fiber. The fibers eventually break. The net result: the hair doesn’t seem to grow. When you get rid of the split ends, the hair is healthier and stronger and can grow longer without breaking easily.

3. Can I get rid of split ends without cutting my hair?
Nowadays there are several products that claim to seal the split ends. These are temporary solutions that can prevent further damage to the rest of the hair. However, the efficiency of these products is yet to be proven. Hair that is damaged will not heal itself and seal back again. Masking the split ends is temporary: there is only so much wear and tear that hair can endure. Eventually a hair cut will be needed. The good news however, is that those products can prolong the time frame between your hair cuts. [More about split ends here]
4. Can I turn gray overnight?
Thank god NO. Turning gray is a gradual process. It happens when the melanocytes at the hair follicles stop producing melanin. Melanin is the pigment that gives hair its color. All the melanocytes don’t stop working at once. This happens over time due to various factors ranging from genetic, to hormonal (stress related) or even medical infuences. Eventually the hair turns completely gray/white as it is completely deprived of melanin. That is one of the reasons that will sometimes notice that half of your hair is colored while the other half has turned gray. [Read here: How does hair turn gray?]
5. Are silicone products damaging to hair?
Silicones as such do not damage hair. If anything, they provide lubrication to hair to prevent damage from friction. However, they tend to leave residues on hair and create build-ups over time. This is accompanied by the need to shampoo more often, which sets you on the path to more damage. Shampooing, drying, combing, heat styling etc. are all sources of damage to the cuticles of the hair. The water soluble silicones can help diminish those outcomes because they don’t build up on hair as much. [Read more about the types of silicones here]
