Here are some remedies and solutions for stronger and thicker hair:

1. Healthy Diet: Consume a balanced diet rich in vitamins, minerals, and protein to nourish your hair from the inside out. Include foods such as eggs, fish, nuts, leafy greens, fruits, and vegetables.
2. Scalp Massage: Regular scalp massages with essential oils like coconut oil, almond oil, or castor oil can stimulate blood flow to the scalp, promoting hair growth and strengthening the hair follicles.
3. Protein Treatment: Apply a protein-rich hair mask once a week to strengthen the hair shaft and prevent breakage. You can use ingredients like egg, yogurt, or mashed avocado for a DIY protein treatment.
4. Avoid Heat Styling: Minimize the use of heat styling tools such as hairdryers, straighteners, and curling irons, as excessive heat can weaken the hair and lead to breakage.
5. Trim Regularly: Get regular trims every 6-8 weeks to remove split ends and prevent further damage to the hair.
6. Avoid Tight Hairstyles: Avoid hairstyles that pull on the hair follicles, such as tight ponytails, braids, or buns, as they can cause hair breakage and traction alopecia.
