Washing your hair with a bar of soap is possible! It simply has to become a hair habit and at the beginning, you have to persevere a little. If necessary, it can be supplemented by rinsing with a mixture of 10% cider vinegar and 90% water. For even more radiant hair!
Afterwards, a single bar in your toiletry bag will be enough to make you feel clean.
Choose your hair type to get the most out of it!
