A chemotherapeutic treatment contains aggressive components, which target your cells, including your scalp’s cells. The main consequence of this treatment is a loss of hair and a weakening of its root. It then needs time to be able to function normally.

Four or six weeks after the last treatment, in most cases, your hair growth starts again, with around 1 to 2 cm per month. Your hair won’t get its shape back right away. Your first hair will be thin and tend to be scattered. Another possible side effect is a change in the appearance of your hair. It can become curly, turn lighter or darker compared to what you’re used to. Radical changes are extremely rare but may also happen. Don’t worry, your hair will most likely return to its original appearance after a dozen of months.


If its look truly disturbs you, it is possible to ask a diagnostic from a dermatologist to know the possibilities open to you. You may feel like your hair is thicker. Rest assured, short hair always seem more robust. This will disappear with time.

The roots of your hair was treated harshly by the chemotherapeutic treatment and it could use special care. We advise you to less aggressive shampoo until a dozen months after the end of your treatment, to let the residues go away.

You can go to your hairdresser once your hair reach 2 cm in order to equalize your hair and see it grow with a nice form. If you intend to color it, be aware that even if it’s possible to do it around a month after your treatment, it is advised to wait at least 6 months. Your hair will then be in a good enough state to endure to receive a coloration. Whichever you choose, favor vegetal colorations without ammoniac or resorcin. These products are toxic for your hair.


You can complement the REDACTIV care with other techniques in order to increase your hair growth to the maximum. Head massages with a bio oil will allow the scalp’s blood circulation to flow more easily. The ricin, for example, brings vitamin E to benefit the hair by strengthening its root and your eyelashes, eyebrows and nails. Some light circular massages with the tip of your fingers, lasting 2 or 3 minutes, will protect your hair and foster its growth.

A healthy diet will boost your hair’s metabolism. Food rich in proteins, minerals such as iron, zinc or magnesium or even B vitamin will benefit greatly to your hair.

The effects of such a diet take about 6 months to be visible on your scalp. We advise you to start it towards the end of your chemotherapeutic treatment.


Some advices concerning hair growth following a chemotherapeutic treatment are given and followed without being true. Indeed, wearing headscarves doesn’t slow down your hair growth, as some people assert. It protects your scalp without any side effect, as growth depends on the root of the hair and not its end.

In the same way, shaving your hair after letting it grow one month will not strengthen it : it does not have any impact on your hair’s roots.

Tying up your hair with elastics will tend to pull out your hair. If your hair has grown back to the point where you can tie it up. Don’t do it as it will probably slow your hair’s growth.


During a chemotherapeutic treatment, your eyelashes and eyebrows will fall a little later than your hair, or even at the of the treatment. It’s not painful but it can cause some irritation until they fall. Some alternatives do exist to hide their loss and some other are to be avoided, such as mascara : it stretches your eyelashes and risks tearing them out. That’s also true for cleansing tissues. A soft approach will turn out better for you. For example, an eyeshadow will create an illusion of relief if your eyelashes grow back thinner than before.

Finally, your eyelashes and eyebrows will most likely grow back soon after the end of your treatment but it depends on the person. Their density while growing back will also change from one individual to the other.
