The aim of this study was to develop and evaluate the efficacy of a multifunctional hair care formulation-Hair BB Cream-containing botanical extracts of Camellia sinensis, Vitis vinifera, and Euterpe orleacea, vitamins, amino acids, UV filters, and silicones for hair treatment and prevention of UV damages. The in vitro antioxidant activity of the botanical extracts was evaluated using the DPPH and chemiluminescence methods. A tensile test, combability, shine, and image analysis were performed to evaluate the efficacy of the formulation. To evaluate protection against UV damage, the hair strands were submitted to UV radiation without and with the application of the Hair BB Cream. The results showed that the application of the Hair BB Cream promoted a reduction in combability values and an increase in break stress and gloss values. After exposure to UV radiation, the hair treated with the BB Cream formulation showed no difference in the mechanical properties test, indicating protection against UV damage. In conclusion, the multifunctional formulation showed several benefits of single product acting in the prevention of UV damage and the treatment of hair damage. Thus, the Hair BB Cream proposed can be suggested as an effective multifunctional hair care product.

A combination of the techniques used in this study permitted a better understanding of nonconventional hair straightener treatments and also supported the choice of the better treatment, considering a good relationship between efficacy and safety. Thus, it is very important to determine the properties of hair for the development of cosmetics used to improve the beauty of curly hair.

Background Oily skin and hair not only contain a large amount of sebum, but also exhibit other changes that compromise their physiology. The immediate effects of dermocosmetics are very important for adhesion to treatment. Aim The aim of the present study was to characterize oily skin and scalp, to evaluate the correlation of sebum production with porphyrin counts and the immediate effects of topical formulations for sebum control. Patients/Methods A total of 100 women aged 18‐49 years were recruited. Sebaceous gland activity, sebum amount, stratum corneum water content (SCWC) transepidermal water loss (TEWL), skin gloss, amount of porphyrins and pores were determined in the face and SCWC, sebum amount, porphyrin count, and TEWL were also determined in the scalp. The immediate effects of formulations containing a guarana extract were determined after 2 hours of application. Results A correlation between sebaceous gland activity and presence of porphyrins in the frontal region of the face was detected. Low gloss values and large amounts of pores in the malar region were related to lower skin uniformity. High sebum values and low SCWC and porphyrin count were also observed in the vertex region. The studied formulations reduced the sebum content of face and scalp after 2 hours of application. Conclusion Oily skin and hair showed high sebum values, which were correlated with porphyrin count and with the activity of sebaceous glands. Finally, the studied formulations had immediate reducing effects on sebum amounts on the skin and scalp.

Considering the growing interest and consumption of hair care products, given that Brazil is the third world market for personal hygiene, perfumery and cosmetics and the second world market for hair cosmetics, 2 the Research and Development of innovative and effective products is of fundamental importance. Thus, there is a growing interest in researches that evaluates the hair damage caused by environment and chemical treatments, as well as the development of formulations that meets the consumer's needs. 3,4 Previous studies of our research group have shown that hair care is of prime importance for the quality of life and well-being of women, since hair plays a significant role in women's body image. 1 Several ingredients have been used for hair cosmetics, such as proteins, amino acids, vitamins, conditioning agents, sunscreens, plant extracts and mainly silicones, due to their low cost. Silicones are used for hair treatment due to its properties, which allows it to deposit on the surface, forming a uniform film, 5 giving the feeling of conditioning in the fiber. However, the use of silicones promotes only a superficial treatment of the fiber. Thus, substances of natural origin such as vegetable oils are now being explored by the cosmetic market. Vegetable oils are natural compounds, derived from oleaginous plants, which presents several benefits to the human body, skin and hair. The vegetable oils are

Introduction Hair appearance and hair care are related with self-steam and quality of life. The way hair looks it is important for women and men and can impact in self-image. 1,2 At the same time, oiliness is a condition that also affects negatively the image and self-esteem. Caused by the excessive oil production in enlarged sebaceous glands, oiliness gives skin and hair scalp a greasy appearance. 3 This way, as oiliness is a constant concern, the search for active substances that helps in oiliness control it's a challenge for Research & Development area. Seaweeds are much known for its use as foods, mainly in East Asian countries as Japan, China and Korea. Despite its use as food, seaweeds have potential to be applied in nutrition, pharmaceutical and cosmetic industries due to its rich composition. Microalgae are a type of seaweeds that convert solar light in bioactive compounds attractive for commercial interest. 4,5 In this context, Spirulina platensis and Ascophyllum nodosum are microalgaes have potential to be used in cosmetics, due to its countless properties. The Spirulina platensis used in our research is obtained by biotechnological process and is rich in pro-vitamin A, vitamins of the B complex, pigments, minerals, proteins, fatty acids, amino acids and polysaccharides as glucose, galactose, mannose and ribose. 6 Ascophyllum nodosum is rich in vitamins A, B and C, minerals, proteins, fatty acids, pigment, amino acids and aspartic and glutamic acids. 7,8 Considering Spirulina platensis and Ascophyllum nodosum composition, they have anti-bacterial, antioxidant and anti-inflammatory properties. 4,6,7 Considering the rich composition and properties of Spirulina platensis and Ascophyllum nodosum, previous studies of our research group 9,10 showed that microalgae have potential to act in skin and hair oiliness control and in the improvement of hair fiber conditions providing better nutrition, hydration and strengthening.

Technological progress has allowed women to change their natural hair configuration according to their will. This type of treatment is very popular around the world, even involving the use of prohibited chemicals, such as formaldehyde. Studies of hair characterization, straighteners and toxic evaluation are available in the literature, although few studies have evaluated the consumer profile or the current legislation of Brazil and the European Union (EU) and its influence on the consumption of hair straighteners. Previous studies from our research group have shown that hair care is essential for the quality of life and well-being of women. Within this context, the present study aimed to evaluate the profile of Brazilian hair straightener consumers, as well as the legislation of Brazil and the EU and its influence on the use of these products. The consumer profile was evaluated by applying questionnaires and the legislation was examined using documental and bibliographic exploratory research. The results provided a full understanding of the current legislation of Brazil and its similarities to EU legislation. It was observed that over 50% of Brazilians currently use or have previously used hair straightener products, even persons who do not have curly hair, suggesting that straight hair is more attractive for today's society. Although the study participants consider the current legislation to be important, over 40% do not know the active ingredients present in the hair straightener they use. Finally, the legislation is not considered in terms of the daily hair treatment routine, with the esthetic result being more important to the consumer.
