If the hair loss is short-term, it may be useful to take food supplements temporarily. However, eating a balanced diet is healthier and does not require supplements.
To learn more about hair and scalp hygiene, explore responses from dermatologists and allergists to questions submitted by internet users during chat sessions organised by Bioderma.
Hair dyes, if they do not cause irritation, do not trigger hair loss. They are therefore not problematic in this case.
The sun dries out and discolours the hair. The hair protects the scalp from the sun. If the hair is sparse, the scalp will need to be protected, like the rest of the body, from possible sun damage.
That is an ancient notion that is not completely false. However, its effect remains limited.
Of course, the hair also needs protection. Protective oils with a sun protection factor are available in pharmacies or at your hairdresser’s.
A balanced diet is more useful than food supplements. A hormonal treatment prescribed by a doctor can improve the hair’s condition in the pre-menopause period. The dye that you use should be as mild as possible.
One single molecule has proven to be effective over time when applied locally in the case of chronic hair loss: minoxidil.
You should keep washing it every two days with a shampoo designed for frequent use. Be sure to finish with cold water. Here’s a tip: tell your hairdresser to give you a few highlights.
Androgenic alopecia (lack of hair) on the top of the scalp (vertex) can be related to hormonal factors and ageing. This phenomenon is indeed influenced by heredity - but not just that. Perms could promote increased hair loss if they are aggressive and repeated.
Losing hair a few weeks after giving birth is a common and normal phenomenon. During pregnancy, almost of all a woman’s hair is in the growth phase (the anagen phase). After childbirth, this phenomenon stops and a higher percentage of hair enters the shedding phase (called the telogen phase). This hair loss is in fact physiological. It can continue if there is an iron deficiency, so this may be something to watch for. While this phenomenon is particularly observed when you wash your hair, shampoos are not responsible and should be used as usual.
Ultraviolet light does indeed damage hair. It becomes lighter, more fragile and more brittle when the keratin lamellae it contains are damaged. You can use hair products containing solar filters to try to reduce this damage.
Your hair should be washed when it’s dirty. If you need to shampoo your hair every day, it is okay as long as you use a mild shampoo (for example, the shampoos in the Nodé range). If a woman has very greasy hair and is on birth control, she will need to choose a different shampoo.
A conditioner can be useful for dry and damaged hair. It may not be necessary if the responsible factors are eliminated (aggressive shampoos or brushing, etc.).
You should see if external factors may be causing these changes. These may include aggressive shampoos, high heat sources, blow drying or occlusion (hat, cap, helmet, etc.).
If there are no medical causes behind the hair loss, the best strategy will be to limit local traumas. In the case of androgenic alopecia (constitutional hair loss in men or women), a treatment may be prescribed by a dermatologist.
