Steps of washing pure natural tea dregs: 1. Each time the dosage is about 50-80g, wrap it with gauze (towel or stockings can also be used), tie the mouth of the bag tightly, and boil it in boiling water for about 10 minute (so that the ingredients in the tea residue can be quickly added into the water). Of course, you can also soak this cloth bag in freshly boiled water (note: if boiling water is used, the amount of tea residue needs to be increased by one). When washing your hair, the water temperature can be higher (as long as it can bear it), which is more conducive to the effective ingredients in tea cakes entering your hair faster. 2. At this time, the water is almost cold, so you can put your hand into the water and rub it repeatedly, so that the ingredients in the tea cake will come out soon, the water will become darker and more turbid, and there are many delicate white bubbles. Then use this water to wash your hair, and the washing time is uncertain. But try to soak your hair in the water of dead tea leaves and absorb the hair care ingredients in the dead tea leaves, so that it will be effective. It takes about five minutes, and some people get it in one minute, but the effect will not be felt for a while ... Of course, in order not to waste, give full play to the role of dead leaves of tea, wipe your hair with a cloth, rub it, massage it properly, and finally wipe your hair clean. 3. Hair just soaked in water will feel a little dry, but when washed with tea leaves, a little vinegar (or beer) will be dropped into the water during rinsing, which will obviously feel softer and smoother when washed, and will obviously feel smoother and more shiny after drying, which is more conducive to the health of hair and scalp.
