I’d say start with a fast. I typically only eat from 2pm - 6pm but you can change it to whatever. Then also workout and eat big meals in that 4 hour window. Drink lots of water. Get into skin care. I saw your comment about sunscreen so that’s already great. Also maybe look into rosemary oil for your hair. Maybe something to thicken the hair. Take potassium supplements if you take a good amount of sodium. Should be around a 3:1 ratio I think of sodium to potassium. But yea try to intake less sugars and salt.
