Replacement of the natural fingernail usually takes about:

The replacement of a natural fingernail typically takes about 4 to 6 months to fully regrow from base to tip. This timeframe considers the average growth rate of fingernails, which is approximately 1/8 inch per month for most individuals. Factors such as age, health, and nutrition can influence this growth rate, but the standard duration for a complete nail replacement remains within that 4 to 6-month range.

Other provided time frames either underestimate or overestimate this period, making them less accurate. For instance, 4 to 8 weeks is too short for a full nail replacement, as it does not account for the necessary time for the nail matrix to produce a completely new nail plate. Similarly, durations of 2 to 8 months and 6 to 12 months either range too broadly or suggest a longer replacement period than is typical for fingernails. Thus, the choice of 4 to 6 months is the most precise and reflects the expected nail growth process accurately.
