A method for dyeing hair is disclosed. The method comprises (1) treating hair with an oxidative colorant agent (A); (2) subsequent to (1), treating the hair with a CH-acidic hair dyeing agent (B); and (3) subsequent to (2), treating the hair with a cosmetic decolorizing agent (Ox). The method comprises a time interval between (1) and (2) of from about 1 minute to about 1.5 months, and a time interval between (2) and (3) of from about 1 minute to about 1.5 months. A process for multitonal dyeing of hair is also disclosed. The process comprises preparing an oxidative colorant agent (A); treating hair with the agent (A) to give a colored hair; preparing a CH-acidic hair dyeing agent (B); treating the colored hair with the agent (B) to give a dyed hair; and treating the dyed hair with a cosmetic decolorizing agent (Ox) to give a multitonal dyed hair.

The present invention primarily relates to a method for producing an aromatic blend comprising unsaturated dienals. The invention further relates to aromatic blends obtained or obtainable by a method according to the invention and compositions or semi-finished products for producing said compositions, comprising aromatic blends according to the invention. A further aspect of the present invention relates to the use of an aromatic blend according to the invention for aromatizing a composition, preferably a composition serving for food or pleasure, or a semi-finished product for producing such a composition.

Natural antiperspirant compositions comprising benzaldehyde, honokiol or capsaicin and their method of use.

The present technology provides a nail coating system suitable for improving a nail plate. The nail coating system includes an oil-based serum and a base composition. The nail coating system may further comprise a UV/LED composition. In use, the oil-based serum may be applied directly to a nail plate without first cleaning the nail plate with alcohol and/or acetone. The oil-based serum coat may fill in any crevices in the nail plate and restoring sebum and water on the nail plate. After the oil-based serum layer is buffed into the nail or dried, the base composition may be applied. After the base composition dries, the UV/LED composition may be applied and cured. Next, a user may apply a nail polish and/or a top coat to the UV/LED composition. The nail polish and/or top coat layer may be removed with traditional nail polisher remover while still maintaining the original coatings of oil-based serum, a base composition and a UV/LED composition. A new nail polish and/or top coat may thereafter be applied to the UV/LED composition.
