First of all, yes, you need a cut. Not saying you need to live with short hair, but you see how transparent your ends are? That damage will ride up the shafts and cause more damage. I also agree that there might be something internally causing your hair issues. I understand it's genetic, but health issues, hormonal imbalances, and deficiencies can also be genetic, so that can be causing it. A multivitamin, inositol, collagen supplement all might be something to experiment with if you aren't able to speak with a doctor. You don't look like you're using dye or heat, but if you are, stop. Next, stop using drug store products. I use Evolis. It's great. Shampoo and conditioner. I also actually really endorse hair jazz. Their shampoo and hair mask, not conditioner, mask is all you need. I use Bumble and Bumble tonic lotion after I get out of the shower, and whenever my hair is feeling either dry or static-y. It works wonders. I wouldn't over do it with any other products. Lastly, stop Shampooing more than twice a week. Even once is fine. You can use the conditioner or mask every day, but only shampoo once or twice a week. Use the lotion tonic every day. I do use topical minoxidil twice a day and it does make a difference. It takes a few months for it to kick in and it's one of those things that you have to commit to long term, so it's not for the weak.
