Sugary Foods & Drinks (Soda, Candy, Pastries)
Excess sugar weakens collagen and keratin production, leading to brittle nails and hair breakage.
White Bread & Refined Carbs
(Pasta, White Rice, Crackers) These spike blood sugar levels, causing inflammation that can weaken hair follicles and slow nail growth.
High-Mercury Fish (Swordfish, King Mackerel)
Excess mercury can lead to hair loss and brittle nails over time.
Dairy (in Excess) (Cheese, Whole Milk, Ice Cream)
Can increase oil production in the scalp, leading to clogged follicles and dandruff.

Excess sodium dehydrates the body, making hair and nails more brittle.
Diet Sodas & Energy Drinks

Effects 
1. Hair Loss (Shedding and Thinning)
A lack of protein, iron, zinc, and essential vitamins (especially B vitamins and vitamin D) can weaken hair follicles, leading to increased shedding and thinning.
2. Brittle and Dry Hair
Deficiencies in omega-3 fatty acids, vitamin A, and biotin can cause hair to become dry, brittle, and prone to breakage.
3. Slower Hair Growth
Without enough protein, iron, and vitamin B12, hair may grow much more slowly or stop growing altogether.
4. Premature Graying
Low levels of vitamin B12, copper, and antioxidants can disrupt melanin production, leading to premature graying by reducing the pigment that gives hair its natural color.
5. Increased Dandruff and Scalp Issues
A lack of zinc, vitamin D, and essential fatty acids can contribute to a dry, flaky scalp, leading to dandruff or even seborrheic dermatitis.
6. Loss of Shine and Weak Hair Structure
Deficiencies in keratin-building nutrients like sulfur, cysteine, and silica can make hair dull and weak.
