Many people believe that a healthy scalp means healthy hair. It's wrong. This is one of the most common mistakes when it comes to hair. Each of our hair grows for 2 to 7 years before falling out. Some external or internal factors (of our own body) can damage our hair while the scalp remains healthy. It doesn't have much to do with hair damage.
So how do you distinguish the true from the false? We hear everything about hair; the latest, the new secret, and our best friend's best recommendation - how to speed up hair growth, how to have better hair, how to have fuller hair, how to avoid brittle hair. Everyone has their theories and tips for keeping their hair healthy or making it grow faster.
Lets Bust Some Hair Myths
"It's better to brush your hair when it's wet."
When washing, water molecules fit between hydrogen bonds in the hair. Wet hair is thus more stretchy than dry hair. This does not matter because these hydrogen bonds close during drying. It also means that damp hair is 50% weaker than dry hair. If you comb or brush them before drying, the force exerted on the hair increases, increasing the likelihood of breakage. This phenomenon is caused by damp hair stretching more than dry hair before it breaks. Wet hair has a significantly higher coefficient of friction than dry hair. This is also why it is much more difficult to comb/brush them in a wet state.
"Finishing the rinse with cold water makes the hair shine."
This rumor is based on the premise that cold water closes the cuticle (surface) of hair. However, the hair is not alive. There are no active mechanisms (e.g., opening and closing the cuticle) caused by hot or cold water. Under the effect of the water which penetrates the hair, the cuticle swells slightly. This phenomenon is nevertheless observed with both hot and cold water.
"The more you cut your hair, the faster it grows."
The hair grows at the root, and the body cannot recognize when it has been cut (shaving, plucking, or tweezing is another story). Cutting the hair helps to remove split ends, which helps in better orientation and a healthier look of the hair. If we often have our hair cut, we probably notice the speed of their regrowth.
"If you pull out a white hair, it will grow back more."
Once a white hair begins to grow, all-new hair coming out of the same follicle will be white. If a hair is pulled out, the follicle again enters an anagen phase (the first phase of hair growth) and produces new white hair. No evidence pulling out white hair causes other hair follicles to start producing white hair.
"Brushing enhances the beauty of the hair."
The brushing's mechanical action damages the hair, breaks the bonds in the cuticle, and weakens the hair over time. Friction on the capillary cuticle (surface) breaks some small parts of the cuticle that come up due to other damage. This way, the strands can orient themselves better, and the hair looks temporarily healthier. However, brushing is increasingly damaging the hair and making it less resistant to chemical, environmental, physical, and thermal aggressions.
Here Are Some More Hair Facts
- On average, we have between 80,000 and 150,000 hairs on our heads.
- Once damaged, our hair can no longer heal. This is why it is so important to protect it.
- A hair is normally made up of keratin (79%), water (17%), and fats, oils, and pigments (4%)
- The life cycle of a hair is usually 2 to 7 years.
- It is the second-fastest tissue to replicate in the human body.
- A hairstyle sags faster with too hot drying of the hair.
- There are four types of hair damage: thermal, chemical, mechanical, and caused by UV.
- Mechanical assault is the most common form of hair damage. It results from brushing, towel drying, and running fingers through hair.
- Towel drying causes mechanical damage to the hair. If you prefer this method, it is better to wrap your hair in a towel and let it dry naturally.
- Hair is weaker when wet. This is why they should not be attacked too much when they are wet.
- A healthy and balanced diet helps to have beautiful skin and beautiful hair.

Suffering from hair loss?
Hair loss is indeed a complicated process and is subjected to individual experience. A person could suffer from alopecia from a tender age or not at all—it is entirely different for each individual. Many of us cram through the internet looking for ways to prevent hair loss. However, no hair loss prevention method as of yet is conclusive.
A hair specialist can not only help you understand the cause of your hair loss, but also help you restore your crowning glory. Advanced medical treatments such as microneedling, PRP hair treatment, cyclical vitamin therapy and hormonal imbalance correction can prevent hair loss and promote hair regrowth.
