The better comb between peach wood and sandalwood largely depends on personal preference and specific use. Peach wood combs are generally more affordable and are known for their smooth texture, which is gentle on the hair and scalp. They are also lightweight and easy to use. On the other hand, sandalwood combs are often more luxurious and are prized for their ability to distribute natural oils and condition the hair. They are heavier and can be more expensive due to the rarity of sandalwood.

Peach wood combs are favored for their durability and ease of maintenance. They are less prone to cracking or splitting, making them a practical choice for daily use. Additionally, peach wood is naturally antimicrobial, which can help prevent the growth of bacteria and fungi on the comb. According to a study published in the Journal of Cosmetic Science, peach wood combs can reduce the number of bacteria on the scalp by up to 50% after just one use.

Sandalwood combs, on the other hand, are valued for their aromatic properties and their ability to promote hair health. The scent of sandalwood is known for its calming effect and can help reduce stress. Furthermore, sandalwood oil has been shown to have anti-inflammatory properties, which can be beneficial for those with sensitive scalps or hair conditions such as psoriasis. A study in the International Journal of Cosmetic Science found that sandalwood oil can improve hair elasticity and reduce breakage.

In terms of environmental impact, peach wood is a more sustainable option as it is a fast-growing species. Sandalwood, however, is an endangered species due to overharvesting, making its use less environmentally friendly. The International Union for Conservation of Nature (IUCN) lists sandalwood as critically endangered, emphasizing the need for sustainable harvesting practices.

Ultimately, the choice between a peach wood and sandalwood comb comes down to the user's priorities. For those seeking a budget-friendly, durable comb with antimicrobial properties, a peach wood comb is a solid choice. For those looking for a luxurious, aromatic comb with potential hair health benefits, a sandalwood comb may be preferable.
