SKB Reference Question

How strictly are references on the SKB enforced. For example, tcp_transmit_skb() clones the SKB and adds a TCP header. Can I assume that in case of re-transmission the header added will be there and can be reused instead of creating a new one from scratch. Some fields like time stamp would need to
