Vinegar Rinse and Finer Hair

Q: Hello, I wanted to know what the cause of the following could possibly be: My hair texture seems to have become "finer". It's not falling out or breaking, but the strands themselves have become finer. I'm wondering if this has something to do with scalp problems. I have had horrible dandruff/flaky scalp for as long as I can remember. I can't tell if my hair is becoming healthier and more manageable or weaker.
My brother had this thinning happen to him before when he started using Nioxin dandruff shampoo, ( I think that was the brand) and he used a thickening shampoo to fix it. I started doing vinegar rinses and I'm wondering if maybe that can be the cause (although it does help my scalp)? I would really, really appreciate advice!

A: Well, using a vinegar rinse frequently could have that affect on the hair. Since vinegar is an acid, it can lower the alkalinity in the hair and can result in a contracting of the cuticle layer. As the cuticle contracts, the hair seems to shrink and appear smoother and shinier and also seems finer in texture.
The fact that you have said that the hair hasn't been falling out or breaking leads me to believe that your hair isn't getting weaker, just more compact. Weakening of the hair would lead to more breakage and noticeable signs of damage. The tightening of the cuticle actually makes the hair more resistant to potential damage.
However, if you aren't happy with the texture of your hair, you should consider reducing the frequency with which you use the vinegar rinses. Since the reason for using the vinegar is to deal with dandruff flakes, perhaps you could add in a dandruff treatment shampoo to your hair care routine. Simply replace every third shampoo session or so with the dandruff shampoo and cut back on your vinegar rinses by half.
You may need to play around with the schedule of uses, but you should be able to find a balance between your scalp management needs and keeping your hair feeling thicker and fuller.
