“…It should be noticed that certain nanosystems can only be used in some formulations, rather than all of them, depending on the cosmetic category and/or intended use. An additional reason for this is that, in some cases, there may be incompatibility between the nanosystem and the other cosmetic ingredients [92,93]; some metal oxides, such as zinc oxide, are very difficult to formulate at acidic pH [94]. Moreover, some nanosystems can alter the mechanisms of action of surfactants/emulsifiers and gelling agents, decreasing the stability of the final cosmetic products.…”

Nanosystems exhibit various innovative physico-chemical properties as well as a range of cosmetic functions, including increased skin retention for loaded compounds. The worldwide nano-market has therefore been consistently extensive in recent decades. This review summarizes the most important properties of nanosystems that are employed in cosmetics, including composition, functions and interactions with skin, with particular attention being paid to marketed products. Moreover, the worldwide regulatory landscape of nanomaterials used as cosmetic ingredients is considered, and the main safety concerns are indicated. In general, advanced physico-chemical characterization is preliminarily needed to assess the safety of nanomaterials for human health and the environment. However, there is currently a shortfall in global legislation as a universally accepted and unambiguous definition of a nanomaterial is still lacking. Therefore, each country follows its own regulations. Anyhow, the main safety concerns arise from the European context, which is the most restrictive. Accordingly, the poor dermal permeation of nanomaterials generally limits their potential toxic effects, which should be mainly ascribed to unwanted or accidental exposure routes.

“…Novel delivery approaches to hair applications such as nanotechnology have emerged as more effective alternatives with the purpose of encapsulating and providing time and site-controlled release of cosmetic ingredients. Nanotechnology-based formulations improve the stability of bioactives, which may result in an overall improvement of efficacy [4][5][6][7]. Moreover, due to the higher residence time of the active whether with the scalp or the hair shaft, nanocarriers have a suitable safety profile.…”

Objective: Nanotechnology has been intensively applied to the development of novel cosmetic products for hair and scalp care during the last decades. Such a trend is corroborated by the fact that about 19% of the total nanocosmetics registered in the StatNano database are intended for hair and scalp care.Nanotechnology-enabled formulations based on nanoparticles, cyclodextrins, liposomes and nanoemulsions have emerged as novel approaches due to chemical stability and their controlled release. Regarding hair care formulations, nanocarriers can target the hair shaft, hair follicle and scalp. Therefore, they have been used to treat several hair disorders, including dandruff and other hair-damaging conditions.Methods: This review addressed the most important nanocarriers applied to hair-related disorders improvement. Furthermore, the application for hair photoprotection and improvement of hair colour duration by nanotechnological formulations is also approached. Besides, we provided an overview of the current scenario of available nano-based commercial hair products and novel patented inventions.Results: From the patent search, the Patent Cooperation Treaty was pointed as the most important depositing agency while the United States of America has been the most depositing country. On the contrary, according to the StatNano database, Brazil stands out in the hair care worldwide market, and it is also the main producer of hair cosmetics based on nanotechnology. Conclusion:As nano-based products offer several advantages over conventional cosmetics, it is expected that in future, there will be more research on nanocarriers applied to hair disorders, as well as commercial products and patent applications.
