Thank you for this information.
In fact, there is little reliable data showing Nutricap's effectiveness in a situation like this. Most of the data found on the subject is from the general satisfaction of women who have used the product. So it is not clear whether this satisfaction is related to a very large improvement in symptoms or just a small improvement combined with no side effects.
Bref, it is possible to try this product without much fear since, in some people, it does improve the symptoms of brittle hair and nails somewhat and it is usually very well tolerated. A trial of up to 60 days is recommended in this case. If no improvement is seen after 60 days, it is recommended to discontinue its use.
You can also wait for the results of the tests you mentioned in your last message before trying anything. In this case, avoid exposing yourself to very irritating products, such as hair dyes and other chemicals that your hands may come in contact with.
Hopefully it will be helpful,
Alexandre Chagnon, pharmacist
