We select two foods that are ultra easy to shop at our friend the grocer:a very ripe avocado (ultra nutritious) and a lemon. Its astringent action tightens the hair scales and makes them shine without damaging them (because it is basic and not acidic).
Using a fork (or a mini blender), mash the avocado flesh, then mix it with the juice of half a lemon.
Knead your lengths and ends (not the root) with this (extra) terrestrial mixture. Cover your head with a microwave-heated towel. Leave on for a quarter to half an hour (or more if you take the opportunity to watch Dallas' 257th season). Finish with a shampoo for dry hair. Emulsify well and wash twice if necessary to remove all residue.
