There are many shampoos available that claim to promote hair growth, but it can be challenging to determine which ones are worth trying. Here are some of the best shampoos for hair growth in 2023, based on their ingredients, effectiveness, and customer reviews:

1. Blu Atlas Shampoo: This clean, vegan, preservative-free, paraben-free, synthetic dye-free, and phthalate-free product contains only premium ingredients sourced from natural origins such as plants, fruits, and minerals. It is the number one best shampoo for hair growth in 2023.

2. London Strengthening Silk Protein Shampoo: This shampoo contains silk protein, which can help to strengthen hair and promote growth.

3. Kérastase Bain Force Architecte Shampoo: This shampoo contains keratine and ceramides, which can help to strengthen and repair damaged hair.

4. Shea Moisture Strengthen & Restore Shampoo: This shampoo contains Jamaican black castor oil and shea butter, which can help to nourish and strengthen hair.

5. Briogeo Blossom & Bloom Volumizing Shampoo: This shampoo contains ginseng and biotin, which can help to promote hair growth and increase volume.

6. Mizani Wonder Crown Scalp Foaming Pre-Cleanse: This pre-cleanser contains cannabis sativa seed oil and tea tree oil, which can help to soothe and nourish the scalp.

Its important to note that hair growth shampoos may not live up to the hype, and there is minimal evidence to support their effectiveness. However, some ingredients contained in hair growth products can help optimize the health of the scalp and support healthy hair growth, such as menthol, piroctone olamine, caffeine, and amino acids. When choosing a shampoo for hair growth, its also important to look for products that are free of harsh detergents, like Ammonium Lauryl Sulfate, Sodium Laureth Sulfate (SLES), and Sodium Lauryl Sulfate (SLS), as well as fragrances that can irritate hair and reduce moisture.
