Journey to healthy hair!!

I am starting a journey to healthy hair with my daughter, she is 6. Currently she is experiencing a lot of dryness and breakage. We dont have a regimen. I dont really think her hair is growing at this point or it is growing very slowly. I plan to take her to the salon for a really good cut, to get most of the unhealthy hair off.

Her hair is natural. I have been doing a lot of reading and researching This is what I have planned.

Products:: Shea moisture organic raw shea butter; moisture retention shampoo, deep treatment masque and the restorative conditioner ( i will use as a leave in). Spritz:: water, aloe vera juice, jojoba oil and maybe coconut oil

Weekly regimen:: Wash, deep condition, apply leave in conditioner and moisturizer (curl enhancing smoothie) Should i spritz and apply leave in daily? Should I use the curl smoothie daily or would the leave in and spritz be enough for moisture?

Thanks
