Summarize the following:
Cut an avocado in half using a sharp knife and carefully remove the pit. In a clean bowl, mash 1/2 of the avocado with a fork until no chunks remain. You can also spoon the avocado into a blender or food processor and blend for a few seconds until smooth.  Make sure that you use a ripe avocado so that you can easily break down any chunks and mash or blend until smooth. If your hair is very thick and/or long, you might need to use the whole avocado. If you only use half though, you can store the avocado half for future use. For added nutrients, add 1 egg, 1 tablespoon (15 mL) of plain yogurt, 1 tablespoon (15 mL) of olive oil, or a few drops of your favorite essential oil, such as peppermint or lavender. You can mix all of these at once, or just add one or a few of these add-ins depending on your hair type and desired effect. Use a fork to stir, or add to your blender or food processor until your add-in is completely mixed with the mashed avocado.  Olive oil is highly conditioning and can help prevent breakage and promote hair growth. Yogurt helps strengthen your hair and can make it extra shiny. Eggs contain vitamins A and E, as well as biotin, which help promote healthy growth. Essential oils add nutrients and can help mask any unpleasant smells. Avocado alone is rich in antioxidants, essential fatty acids, and vitamins, so feel free to skip this step if you just want to use a simple avocado conditioner.  If you are using the whole avocado instead of just half, double the add-ins. For example, for a whole avocado worth of paste, you will need 2 tablespoons (30 mL) of plain yogurt. Using your hands, scoop up a dollop of the avocado paste and massage it into a section of your hair for about 1 minute. Repeat this process until all of your hair is covered and you have used all of the paste.  If you have really thick and/or long hair, you may need to make a bit more of the paste at this point to cover all of your hair.  It might be a good idea to wear clothes that you don’t mind staining, or you can wrap a towel around your shoulders to protect your clothing. This will give your hair ample time to absorb the nutrients from the avocado paste. You can leave your hair uncovered, or you can protect your clothes and surroundings by putting on a shower cap, or by lightly wrapping your hair in a towel. After you have let the avocado paste sit in your hair for 15 minutes, wash it out thoroughly with water. Once the mixture is rinsed out of your hair, dry and style your hair as usual. Your hair should feel extra soft and smooth. Avocado paste alone should not make your hair greasy or weighed down, so you shouldn’t need to use shampoo to get it all out. If you use olive oil or an egg as add-ins, however, you may need to use your regular shampoo to get all of the treatment out. For best results, condition your hair with an avocado paste once every 2 weeks. This will keep your hair moisturized and shiny without weighing it down. Feel free to experiment with different add-ins every 2 weeks until you find what works best for your hair.

Summary:
Mash 1/2 of a ripe avocado. Mix in essential oils, a raw egg, olive oil, and/or yogurt. Massage the avocado paste into clean, damp hair. Leave the avocado paste in your hair for 15 minutes. Rinse out with water. Repeat once every 2 weeks.
