A hair’s lifecycle has three stages : 

Even though effects are visible on the hair, all the action takes place on the scalp.

How can I keep my hair clean?

For all hair types, you need to cleanse it without irritating it or removing the hydrolipidic film so you do not disrupt the hair bulb’s physiology.

Only a non-detergent shampoo can preserve the hair’s biological balance. This type of shampoo does not contain surfactants that would be too harsh on the hair fibre. You should usually wash your hair every day if you wear a hat, play intense sports or live somewhere with high pollution. So it is critical to choose a true non-detergent shampoo. Some medicated shampoos can be non-detergent.

 

 

What are the signs of abnormal hair loss?

Losing less than 100 hairs per day is absolutely normal because it corresponds to the natural hair cycle. If you lose more than this, you should be concerned about the state of your hair.

When it is not genetic (baldness), excessive hair loss is often related to:

All of these factors will inevitably have an effect on the hair. In addition to hair loss, this may result in fragile, lifeless and dull hair or else oily and fine hair.


Taking a nutritional supplement may be beneficial for hair. In order for it to stimulate, strengthen and densify your hair, this supplement should contain nutrients that stimulate the production of high-quality keratin, limit hyperseborrhoea and promote hair growth. If it is enriched with magnesium, this nutritional supplement may also help combat stress, which can cause hair loss.


If you are experiencing significant and persistent hair loss, you should see a dermatologist.

Key points

Washing hair too frequently and using overly detergent shampoos risk causing reactive hyperseborrhoea. Indeed, when sebum has been removed after aggressive cleansing, the sebaceous glands may get “excited” and over-secrete, thus making the hair and scalp even oilier. 

  • Adopt a balanced, varied, healthy and light diet, composed mostly of fresh vegetables, fruits and cereals, as well as foods rich in essential fatty acids, sulphur-containing amino acids, zinc and B group vitamins (fish, shellfish, liver, eggs, oils, yoghurt, etc.).
  • Adopt a "stress-free" lifestyle. Take time to relax to limit tension.
  • Make up for any deficiencies by taking nutritional supplements.

1/ Massage your scalp before applying your shampoo, performing light circular movements from your neck to the top of your head. This not only stimulates hair growth by improving blood micro-circulation but also optimises the action of specific shampoos.

2/ Use a shampoo and possibly a treatment tailored to your scalp and hair. If you have to wash your hair every day, choose a non-detergent treatment shampoo for daily use.

If the shampoo is medicated, follow your dermatologist’s prescription or your pharmacist’s advice.

3/ Rinse your hair thoroughly with warm water. You should always spend more time rinsing your hair than washing it.

  • Dry your hair carefully. Air-drying is the most gentle method. If you need to use a blow dryer, set it to warm position. Excessive heat attacks the hair, stimulates sweat and sebum secretions and makes the hair static.Brush your hair gently. Brushing should be gentle so as to not attack the scalp and hair shaft. It is essential as it eliminates dirt particles that make the hair dull.
  • Use combs or brushes made with natural materials, and remember to clean them frequently with a shampoo or antiseptic soap.
