No, fingerprints themselves do not change throughout a person's life. The fundamental ridge patterns are formed before birth and remain consistent. However, the clarity and ease of obtaining a fingerprint can be affected by various factors.
Factors Affecting Fingerprint Clarity:
- Age: As we age, skin elasticity decreases, and ridges thicken. This makes obtaining a clear scan or print more difficult, but it doesn't alter the underlying fingerprint pattern itself. [Source: Science Focus, Handonheart Jewellery]
- Injury: Severe injuries, such as deep cuts or burns, can damage the fingertip's tissues, potentially distorting the fingerprint pattern. While the skin may heal and regenerate, the resulting fingerprint might appear different. However, even with significant damage, the underlying pattern often persists.

- Decomposition (Post-mortem): After death, decomposition, desiccation, or soaking can make fingerprints harder to obtain. Nevertheless, advanced techniques can often still recover usable prints. [Source: HowStuffWorks]
Misconceptions:
It's crucial to distinguish between the underlying fingerprint pattern and the quality of a fingerprint image. While the core pattern remains unchanged, external factors can make obtaining a clear image challenging. Claims of changing fingerprints are often referring to the difficulty of acquiring a usable print, not an actual alteration of the fingerprint itself. [Source: Multiple sources]
In Summary:
While external factors can affect the clarity and quality of a fingerprint, the fundamental fingerprint pattern remains unchanged throughout a person's life. The ridge patterns established before birth are unique and persistent.
