Best budget combination hair fix!

My hair has always been important to me, as a teen I thought it was my best feature and often tried to use it to cover my face to hide my acne (I was also very introverted). However, I was blessed (or cursed) with a widow's peak, which after almost a decade of tight plaits (or ponytail if I was lucky), my hairline was retreating at 14. Since then, I had been attempting to keep my hair down to stop the pulling on my thinning hairline and prevent anymore retreating. Then a year ago as I started uni, I decided to do more to take care of my hair. It is very inconvenient as combination hair where my roots get oily (previously also had dandruff) but my ends are dry, frizzy, with split ends for days and would constantly knot. Now, after a year of consistently using my hair mask, leave-in conditioner and hair oil/serum combo, my hair has improved in thickness, has less hair loss when brushing, frizziness has decreased, and my hair won't knot within seconds of brushing it. Another bonus is that my hairline has grown back!
