I wash my hair almost every day and blow dry my hair most days and my hair is in good condition. I won’t recommend specific products, but I will let you know what I look for in the three hair products I use:
I’m not sure what shampoos you use, but I would guess that they might have sodium lauryl sulfate or sodium laureth sulfate, etc. Those aren’t really “bad,” but they are more harsh on hair and strip more oil than most sulfate-free soaps. But not all SLS-free shampoos are sulfate free, and some sulfate-free shampoos are still as harsh on hair. Looking for a shampoo that is color-safe is usually a good bet… The harsher soaps tend to open up the follicles of the hair shaft, which leaches hair dye out of hair and leads to fading, which is to say: to be color-safe, the shampoo has to be gentler on hair. Focus on the roots of the hair, which will be the oiliest, and work the soap down the strands, but don’t really touch the ends, which will be the driest.
Conditioners also make a big difference for me. I look for ones that boast making hair “manageable” or that boast “detangling” hair—those are the conditioners that are rebalancing the pH of the hair shaft most effectively, consequently closing the follicles and leaving the hair smooth and shiny. (The shampoos are slightly base and open up the hair follicles. Color-safe shampoos do this significantly less than other shampoos, but they still do it to some extent. When the follicles are open hair gets somewhat rough, tends to stick to itself making brushing a chore, and dulling the appearance of the hair. Conditioners are for slicking the follicles back down, and conditioners which boast manageability/tangle-free in my experience to do this most effectively… ironically, in my experience, conditioners which boast “shine” usually just use the silicon compounds I’ll mention below—those are coating the hair but not smoothing the shafts.)
I also use a smoothing/shining serum. I like ones with olive oil or argan oil, but the main ingredients are cyclopentasiloxane and/or dimethicone, and/or a few other silicon-based compounds. I put a small amount (maybe a nicke’s worth) in my hair when it’s wet, working it into the hair. The silicon kind of seals the hair from hair-dryer heat damage, especially the ends of the hair. It also helps to smooth out or calm down any frizz associated with air-drying or heat-drying. And, as a bonus, the silicon compounds add another layer of shine to the hair. Focus on the ends of the hair, which will be the driest, and work the product up the strands. Don’t really touch the roots, which will soon be the oiliest.
I know some people have had success with ACV. The theory is that it, like conditioner, balances the pH of the hair. I tried it a couple of times… all I got was vinegar-smelling, rough-tangled hair. But it won’t hurt to try it, and if it works for you, then great!
PS I can let you know my favorite brands if you want! Or you can just experiment… I’ve experimented a lot with hair care products these last couple of years and I’ve finally found a routine that I’m happy with. But don’t experiment with Wen. Not sure you were going to, but I thought I’d just say it… There’s a growing lawsuit and claims that it causes extreme hair loss.
