Abstract: An aqueous external preparation for scalp, that is directly applied to the scalp to improve the elasticity and luster of newly grown or growing hair without affecting the safety or the feeling of touch of the hair, contains the following components (a) a eucalyptus extract; (b) a blood flow enhancer; (c) an anti-inflammatory agent; (d) an acrylic acid/C10-30 alkyl acrylate copolymer; and (e) ethanol. The blood flow enhancer (b) is preferably selected from the group consisting of swertia japonica extract, vitamin E, nicotinic acid and derivatives thereof. The anti-inflammatory agent (c) is preferably glycyrrhetin or derivatives thereof.

Abstract: The present invention relates a hair quality improver containing the extract, steam distillate or pressed product of a plant selected from Eucalyptus, hop, ginger, gardenia, clove or safflower. Use of this hair quality improver brings about an improvement in the quality or touch of the hair such as strength-body, fluffiness, manageability or gloss.

Abstract: The present invention relates to flavanonol derivatives represented by formula (1): ##STR1## (wherein R.sup.1 represents an alkyl group, and each of R.sup.2 and R.sup.3 represents a hydrogen atom, an alkyl group which may have a substituent, an alkoxyl group which may have a substituent, a hydroxyl group, a cyano group, or a halogen atom), as well as to hair-nourishing and hair-growing compositions containing the derivatives. The compounds accelerate differentiation and proliferation of hair matrix cells, thereby exhibiting remarkable hair-nourishing and hair-growing effects.
