This hair spells does not make your hair 4 inches a day. I got 4 inches in 3 weeks which matched a normal hair growth for some people who are not using spells.
~It does work the first time and you will know by the length and hair feeling longer.
You say it 3 times a day. It is your choice~if you want say it every other day or twice a week or every 2 weeks.
Let's say you say it the first time without any messing up or any interruptions. Then the 2nd round, you messed up on a word~it's best to repeat that word clearly OR you can restart the 2nd round. It's up to you.
I've messed up a few times and I had to repeat the word and it is still effective.
