How to make solid shampoo for dull hair

Before you begin

  • If you haven’t tried solid shampoo before, keep in mind that it may take your hair some time to adapt. Solid and liquid shampoos are very different, so give yourself at least three weeks of regular use before reaching a final opinion of this product. That’s about how long it will take for your scalp to adjust to your homemade solid shampoo!
  • In its solid state, SCI (sodium cocoyl isethionate) can irritate your respiratory tract, so it must be handled with caution. Work in a well-ventilated space, wear a dust mask, or both.



Good to know!

  • SCI is the cleansing and foaming agent in this recipe. It’s gentle on your scalp and provides a lovely lather.
  • Bitter orange powder adds shine to your locks. It softens and strengthens your hair and helps detangle it, while also toning your scalp. 
  • Marshmallow root powder sheathes the hair fibre. It also helps protect and detangle your locks.
  • Shea butter deeply nourishes your hair.
  • Argan oil revitalizes dull hair.
  • Castor oil strengthens your hair and sheathes the hair fibre.
  • Ylang-ylang essential oil helps regulate sebum production while strengthening and beautifying your hair.
  • If you love the scent of orange, try adding some sweet orange essential oil to your homemade solid shampoo! Just reduce the quantity of ylang-ylang essential oil by half (use just 1 g) and add 1 g of sweet orange essential oil in step 9, then proceed with the rest of the recipe. The sweet orange essential will not only impart its refreshing fruity scent to your DIY shampoo, it will also tone your scalp.

Use and conservation

This solid shampoo recipe is specifically formulated to add shine to dull hair in winter. It’s very easy to use! Just moisten the bar, rub it between your hands to form a lather, then apply the lather to your hair. Leave it on for one minute and then rinse it off with fresh water. You can also directly rub your scalp with this solid shampoo. 

We recommend doing a vinegar rinse after using any solid shampoo in order to balance the pH of your hair. This will also leave it extra shiny! 

Here’s how to do an apple cider vinegar rinse:

  1. Mix 1 tablespoon apple cider vinegar in 1 litre of water.
  2. When you’ve finished with your usual shower hair care routine, pour the full liter of vinegar water over your hair, with your head pointed downwards. Do not rinse off. 
  3. Dry and style your hair as usual. The vinegar smell will disappear as soon as your hair is dry. 


It’s important to let your shampoo bar dry out between uses. When made in optimal sanitary conditions, it will keep for about six months.
