Hair gloss/ Lamellar water - Any suggestions?

I am 25, female and I have dry hair (i used to have really silky straight hair and it miss them...)

My hairstylist effed my hair up when he gave me a step cut from the back of my hair ( i usually keep it straight) now my hair are frizzy, dry and unmanageable. I hate it.

Trying anything and everything to bring the shine back.

Was considering purchasing this L'oreal Elvive gloss from desertcart (since unavailable in India)

Also found BBLUNT option for 'Lamellar Water'

Which one would you guys suggest that I invest in?

Any one who has used both or either can suggest?
