Keratin Treatment and Textlaxing Afterwards? Help

I’ve done my first keratin treatment back in early December last year in order to step away from relaxers. I usually would relax the new growth (roots) professionally so my hair can be flat, smooth and slick. Keratin treatment barely lasted and only beautifully smoothed and straightened my roots the first week of getting it done (I wash my hair once or twice a week).

I am considering textlaxing my new growth as my roots are still puffy and kinky, esp when coming out of the shower when using a shower cap and even straightening it too.

I want to textlax my hair early next month. Is that too soon, and would this be a good idea to do as I’m only tackling very small parts of the roots?

Thank you!
