CHOOSE HIGH QUALITY HENNA The herbs used to produce BIO HENNA are freshly picked, dried, crushed and packed as quickly as possible. We make sure that BIO HENNA is on the store shelf as soon as possible after harvesting. This is extremely important, because then you get the best color effects and the strongest care effect of BIO HENNA. ORIENTANA HENNAS CONTAIN ONLY PLANT INGREDIENTS Orientana BIO HENNAs consist exclusively of plant parts - heavily powdered, without any additives. They are in powder form. The plants from which BIO HENNA is produced come from crops with which ORIENTANA has long-term agreements and which have certificates confirming organic cultivation. Any henna bush - lawsoni suitable for harvesting must first grow freely in a good place for three years. Henna is harvested twice a year and each harvest has its own individual characteristics. The most valuable and best is henna harvested in November. Very often the quality of henna depends on the time of harvest and on weather conditions. Henna needs good sunny conditions. ORIENTANA HENNAS ARE TESTED Orientana BIO HENNAs are tested in detail at several stages. First of all, the soil in which they are grown is checked at the very beginning. The soil is tested for the presence of heavy metals. ORIENTANA, as a contracted recipient, tests the soil at its suppliers. The most modern, specialist equipment is used for this purpose, such as an absorption spectrometer. The finished product - the BIO HENNA mixture is tested once again for heavy metal content, microbiological tests are carried out for the content of microorganisms, as well as dermatological and apparatus tests. All this to ensure the highest quality of henna for hair dyeing.
