@Lucia can u please post your henna regimen? And what other ayurvedic powders do u use?
I don't have a set schedule for henna just when I need it which is around every 2-3 months or so. It helps keep my hair strong and I have less breakage shedding, splits SSKs when I do regular henna and Ayurvedic treatments. With Ayurveda you have to know which powders do what and is that what you need. Its imoirtant to keep the proper balance of strength and moisture when using Ayurvedic powders. It's like protein moisture balance
Henna: 2 Lemons squeezed strained
Hot water or Rooibois tea I use the tea water to make the henna.
Body art quality henna of your choice. I get mine from mehandi.com no metallics so you can use conventional hair color over it but I would deep condition a lot.
Mix into a thick paste, get the lumps out
Let it sit in covered bowel overnight.
Use from roots to ends add extra henna on ends
Cover with plastic cap
Sit under heat cap for 1 hour or leave it in your hair for 2-3 hours no heat.
Rinse well
Deep moisturizing conditioner under heat cap or steamer for 30m
Leave in products and Style
For my pre-poos I do 2 different methods paste or tea.
The straight paste instructions are in the box. Just boil water mix into a thick paste, let cool then coat scalp massage, then coat hair then let sit on hair for 15m then rinse out, condition.
Tea: I just boil water mix the powders until smooth, let cool then strain, pour over hair rub into scalp squeeze excess wait 5 minutes then rinse out. Then condition or deep condition.
Notice I always condition or DC after these Ayurvedic treatments unless I'm using Ayurvedic oils because I basically use straight henna. I don't add yogurt or do a lot of stuff some other people do because I don't need it, it's just extra work and doesn't give my hair the full potency of the herbs which is what I want. For teas or pastes I also never mix more than 3 different Ayurvedic powders in 1 mixture, cause that could actually harm your hair (overload) or cancel out the effects you want. Now if you need the extras in your Ayurvedic mixes so your hair doesn't dry out please do what works for you.
I also use Curlyproverbs version of using henna or Ayurvedic teas in spray bottle as a strengthening spray. See her video on YT on proper way to use this spray tea.
